What are the differences between the X10i and X10a? - XPERIA X10 Q&A, Help & Troubleshooting

What are the differences between the X10i and X10a? I know the Canadian version (x10a) has a different radio then the X10i (Europe).
This is the Only Differences I could find.
X10I......... GSM850, GSM900, GSM1800, GSM1900, UMTS900, UMTS1700, UMTS2100 .................... HSDPA 7.2 Mbit
X10A........ GSM850, GSM900, GSM1800, GSM1900, UMTS800, UMTS850, UMTS1900, UMTS2100 ...... HSDPA 10.2 Mbit
Is there else anything that might be different??

As far as i know, no.
Only the 3G frequency which is different in north america (well, only for some carriers).
Rogers, afaik is using 850 so you need X10a otherway no 3G

i think the HSDPA speeds are the same for both, the only difference is one of the 3G bands
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 1700 / 2100
HSDPA 850 / 1900 / 2100 - X10a for Americas

Is there a way to convert between the X10i and the X10a?
Please advise if there is a tutorial link or something.
Thank you for your help.
Regards L

You can't do that.. maybe if you change the Chip..

X10a has 800/850/1900/2100 WCDMA and quad band GSM/EDGE
X10i has 900/1700/2100 WCDMA and quad band GSM/EDGE
'a' uses QSD8650 processor 'i' uses QSD8250
800 WCDMA band if anyone wonders is for DoCoMo in Japan.

Hello. How can I identify which one I have?
Thanks!

X10 in Canada
In this case, for the Canadian market, I believe the X10i is compatible with Wind Mobile (1700), while X10a is with Rogers/Fido/Chatr. Am I wrong?

you are correct, for HSPA rogers, bell, and telus are all on the 850 and use x10a
wind mobile has the same frequency as t-mobile USA so x10i would work. however wind mobile is only available in select very few markets

I have a X10i and can receive 3G on Rogers in Canada. On the side of my box it says UMTS/HSPA Band 1/2/5/6 (Along with the quad band GSM), can someone explain to me what the numbers mean?

odd ...
That's odd because I have a x10i and it says UMTS/HSPA 1/4/8
I also don't know what these numbers mean so basically have the same question.
Where did you get yours from? And are you sure it is a X10i and are you sure you have 3G? Does the data connection icon say "G" or "3G"? I'm asking because based on previous discussion, x10i is not supposed to work on Rogers so I'm very surprised.
Right underneath the bands mine says SV, DA, FI, NO which I believe stands for Sweden, Denmark, Finland, Norway as their localization codes.

It says 3G beside the signal bar, and here are picts of my service menu:
The service menu says I have an X10i
Here are the bands it supports, the service menu has the same band numbers as on my box:
Bought the phone used for the wife. So can anyone explain the band numbers?, as I am not familiar with SE phones, I have always used HTC

According to the UMTS bands table from wikipedia, those numbers mean 2100, 1900, 850, 800
I can't post the link because I'm a new user and the system doesn't allow me to post the links but if you wikipedia umts you'll find it.
I didn't know different x10i's could support different bands. I wonder if this means a different hardware as well or just a software change. Anyone?

I maybe wrong but I did read of people changing the firmware from the 10a to the 10i this will NOT change the radios.. simple way to check is to look under the battery label as the software can be changed.

I used to have an Xperia X1a, and everytime i did flash a rom, my phone was always a x1i, but was fully functional, what i need to do was copy a simple modelname.txt file to the windows folder with x1a in it, and the phone became a x1a, i think that the model we get on the about screen is from some file on the rom, but what really defines the model is the hardware, not the sticker from behind.

Thanks for the info! So does this mean that I really have an X10a that had been flashed? Sorry for the newbie questions, but this is the first time for me playing with an Andriod device. In my phone settings "About phone" is says:
Model Number - X10i
Firmware Version - 1.6 (I assume this is the Andriod version)
Baseband Version - 1.0.10
Kernal Version - 2.6.29-rel
Build Number - R1FA010
Is the build number the Andriod release number? ie. like windows mobile, there is wm6 with build 23xxx?
(I have never flashed the phone since I got it)

for changing from x10i to x10a and vice versa but there r a problem Flashing your Xperia X10i to X10a (and vice versa) will result in SEUS not being able to update your phone for future updates
sry am a new user so send me an email and i'll send u the link

x10 with Wind?

OK done some checking here and did not find a thread about this so I will ask.
I am not the most technical guy but I did manage to successfully unlock my rogers x10a and root it from the x10a to x10i. I was under the impression that if rooted to x10i I would be able to use this phone with Wind. The issue is that wind uses aws 1700/2100 frequency which I read that x10i supports and if rooted would enable those frequencies.
Most of what I have read has been mixed. Some claim they have their rogers x10a working on the wind network after rooting to x10i and some say it won't work.
For me it does not work. I put in my Wind sim card and all I can get is Wind Away and not Wind Home. I am not sure if the reason is it can't be done or I am missing a step somewhere. I know the apn setting but entering them and saving them made no difference.
I would just like to know if its possible and if anyone has been successful using there x10 with Wind?

Hey gmaronski,
As long as it supports the AWS 1700/2100 frequency it will work. By looking at the specs from www.gsmarena.com it appears that it should work. The mini and mini pro look like they would not though. Hope this helps.
Have a great day.

I have this phone on Wind. There are two versions of this phone, x10a (Rogers) and x10i (rest of the world), and as long as you get an x10i, it will work on Wind.
Sorry bad news.
Wind operates on UMTS Band 4 which is known as AWS and operates 1700up / 2100 down. Don't be confused by the 2100 when looking at phone specs, this is a 1700 band. When 2100 is mentioned in phone specs it means Band 1 which is knows as IMT.
X10A supports Bands 1, 2, 5, 6 (2100, 1900, 850, 800)
X10I supports bands 1, 4, 8 (2100, 1700, 900)
Wind is soley band 4, so if you want to have Wind service you will need an X10I.
Changing firmware to X10I WILL NOT change your phone to x10i, this is determined by a hardware chip on the phone, changing software will not change this.
Thanks for the explanation
OK that seems logical to me. Its very confusing though when you read comments like this.

Carrier:Windbasically the x10i is running on the bands of "HSDPA 900 / 1700 / 2100" and the x10a (north american version) is running on the bands of "HSDPA 850 / 1900 / 2100 / 800" now what you can do is flash an x10a with an x10i's firmware and vise versa and that firmware will activate the 1700 band on an x10a if you get what I mean. the radios are interchangeable on each models. for example i've got an x10i and flashed it to an x10a now i'm able to get 3G with Rogers rather than 3G on WIND with the 1700 band because now the phone is acting like its an x10a.
This guy is saying flashing the firmware activates the bands needed for wind. I wish people would know what they are talking about before they write these stupid comments.
X10a does not work with wind. Even if you flash a x10a with the x10i firmware. An x10a will not work with wind. Unless you physically change the antenna on the x10a with the x10i antenna.

Correct
Yes I know from personal experience and Balur's and your comments reinforced it. I was only hoping I was wrong. Guess I will stay with fido for this Phone and Wind for my HTC.
Thanks for the comments.
it is possible to flash software and activate AWS.But I am not sure on X10

For the xperia ion if you SIM unlock it then flash the i version stock ftf, it unlocks bands blocked by att.

[Q] Streak on NextG in australia? UMTS 850MHz

I am currently looking at purchasing a used Dell Streak, it is in Australia (so am I) but the seller says it was originally from the USA. Looking at a few different sites, the spec for American Streaks says UMTS 850. (Eg.: http://forum.xda-developers.com/wiki/index.php?title=Dell_Streak )
The network I would most like to use here is Australia is Telstra's NextG network; it is described here: http://whirlpool.net.au/wiki/3g_for_network_engineers
thus:
""3G" is a broad category of standards and services around "broadband" mobile wireless voice and data. Universal Mobile Telecommunications System (UMTS) is part of this family and is the standard used for 3G services in Australia. Telstra's NextG product is a UMTS implementation using a Wideband CDMA (W-CDMA) radio carrier in the 850 MHz band. There are "legacy" pockets of 2100 MHz used in some areas. Most modems are capable of automatically switching between the two bands, though not always of making the best choice. Some Telstra technical staff recommend sticking to the 850 MHz band."
I know that the Dell Streak version sold here by Optus (Telstra didn't sell them)
was NOT usable on the NextG network, but the info above from the links seems to imply that a Streak built for the USA would be?
Am I correct, or am I missing something?
Thanks, Bernie.
Yes, the US Dell Streak will work on Telstra's NextG.
Currently using it. Getting around 2770kbps down and 1339kbps up.
so um.... hardware should be the same, so a baseband / radio flash + custom mod should enable it?
you running a custom rom or a us standard?
cheers mate
blues
Thanks bluhound,
I'm also interested to know if you can update an Aussie or UK version like live_blues suggests. Any idea?
Thanks, Bernie.
You don't have to flash anything. The US firmware will work with NextG out of the box.
I don't think you will be able to flash an Aussie ROM as only Optus has the Streak and that model operates on the 900Mhz freq, not Telstra's 850Mhz.
I am currently running on StreakDroid 1.9.1 with DSP v360.
Dell Streak FAQ - xda wiki
See the last two lines, roms do not determine/affect your 3G freqs or lock status, it's determined solely by the configuration applied to the device when it was manufactured.
Roms do not care what submodel/lock status you have, you can install any rom and it wont change anything here.
There is also no concept of a AUS rom as the only roms loaded on devices sold there are unbranded/retail (unless they changed it some time during it's lifetime)
thx Manii, so its a manufacturing thingy... interesting... im sporting a UK Streak in Oz, guess I would just have to try

No 3G access on vodafone in India on my ATT SGS2

Hello All,
I am having issues connecting to the 3G network of Vodafone in India. My SGS2 is from AT&T and I was able to root it & unlock it and its works fine with the call and other stuff. I flashed the UnNamed v1.0.4 ROM and its been pretty stable.
But after activating my 3G service here, all I see is E with the 2 arrows. I researched online and saw that we need to change the CSC code. I looked up at the CSC code on my phone by dialing in *#272*<your IMEI># and its shows as ATT.
Can you please help me on how to change the CSC to INU (India Localisation) so that I can access the 3G network here.
Thanks

you probably just need to add your apn. Flash http://forum.xda-developers.com/showthread.php?t=1299705 its based on the international version so it might let you select your network.
First, make sure that Vodafone in India works in UMTS 850/1900/2100mhz bands. If they are using 900mhz band, this phone does not support it. As much as I know most European and Asian countries use either 900mhz or 2100mhz or both.
It could be frequency or any other issue but if you are looking to change your CSC then look up app "Samsung Galaxy S / S2 CSC" in the market and give it a try. Remember that your ROM has to support MultiCSC.
EDGE with data functioning is a clear sign of a band mismatch, not an APN issue.

India is 2100mhz while the at&t sgsii is 850/1900 so 3g won't work. The t-mobile sgsii would work though, t-mobile's 3g frequency is 1700/2100.

AT&T GS2 supports 850/1900/2100 3G bands. So, if the paticular carrier uses 900 for 3G, it won't work.
Or if it happens to use the 1700 MHz AWS band - but I don't know if any Indian carriers do.

1700 seems to be North America exclusive Rest of the world primarily use 900 and 2100 for 3G with Brazil and Austrialia also use 850 and 1900 in addition to 900 and 2100.

Quad-band HSPA 3G Lumia.....such thing?

So on eBay this one vendor is saying that his Lumia 800 he's selling is the international version, and it has the 850/1900 HSPA bands ALONG with the 900/2100 bands.....is there such a thing? I've only heard of the two versions- the European version with the 900/2100 bands and the NA version with 850/1900.
I don't want to buy something and have it not work with my 3G service with Telus, so confirmation would for sure help.
Thanks!

My understanding is there are 2 versions (if we exclude China), the RM-801 and the RM-819. They support the 4 GSM voice bands (850/900/1800/1900 MHz) but differ with the data bands:
* RM-801 with WCDMA HSPA 900/1900/2100 MHz
* RM-819 with WCDMA HSPA 850/1900/2100 MHz
So I believe the eBay vendor is wrong and might be mixing up the voice and data bands.
But don't quote me on this, although I checked Nokia's web site and the full product sheets.
Yeah, I'll have to ask him. He says it isn't compatible with his T-Mo 3G service in the US either.
Would it still operate on Telus' network with just a single 1900 data band? From what I know Telus doesn't run an EDGE network as they had adopted from CDMA to HSPA not that long ago. I guess I'd still get voice services but that kind of defeats the purpose of my data plan.
I guess this leads me to another thing.....how can the vendor find out which rm version it is?
The fellow just posted a picture of the tag, says 801 on the box so that must be it.

I think you don't know about telecommunication implementation. How come you can't get 3G with i-series ??? Have you red that phone specification ???. If u know about GSM and 3G implementation as ido (i work in these telecommunication field as an network engineer implementation). If you read that phone spec --> http://www.sonymobile.com/us/products/phones/xperia-mini-pro/specifications/ (see under Networks) you'll see :
GSM GPRS/EDGE 850, 900, 1800, 1900 so for 2G connection it cover all that frequncies that use in all over the world (except Japan, coz Japanese have different 2G and 3G network implementation) see this --> http://www.worldtimezone.com/gsm.html.
UMTS HSPA 900, 2100 (Global except Americas) so it means it cover all 3G frequencies that use outside America.
UMTS HSPA 800, 850, 1900, 2100 (Americas) so it means it cover all 3G frequencies that use inside America.
So why you're all saying that this phone didn't support you're country 3G, except you want to you use your phone in Japan, then it won't works as Japan use 3G with frequecies 1700/2100 MHz. The only possibility that i know is you're area was not coverage by 3G connection or even if that 3G had implemented in your country but it can't reach you're area so this what we called "Blank Spot" area. So please first get to know how the netrwork implemented in you're are, does it coverage by 3G or not.
For the code series, yeah you're right SK17i - it means for international release outside America and SK17a for inside America but it's not related to the frequencies coverage (notice these). SK17x or Xperia Mini Pro has globally working in all over the world that use 2G frequencies 850, 900, 1800, 1900 Mhz and 3G frequencies 800, 850, 900, 1900, 2100 MHz, except you're using it in Japan so it's useless.

Can u tell me what's your phone name and type that you say it that3G worked before you use this Xperia ???
I use Samsung Galaxy FIT and i can flash over and over again either thru flashtool (SAMSUNG flashtool named ODIN) or CWM, for a day now i've just reflash my Galaxy FIT with 12 ROM (7 Stock ROM and 5 Cutom ROM) with no problem with 3G Connection. In fact, Samsung has more simplicity in the software system. I've SK17i too, but since it's still have developer guaranted and i have this .62 firmware which must downgrade first to .58 then we can rooted so i'm leave it till my developer guarated expired then i'll install custom ROM too. Now plan to upgrade to ICS but Sony announced it'll decrease the performance, so i'll leave in GB for now.
Actually there's a software system which is involve for locking some frequencies for certain country, it calls MNC/MCC code --> http://en.wikipedia.org/wiki/Mobile_Network_Code. You must first unlock this code for using that Xperia Mini Pro in your country. Are your phone comes with bundling from specific Telecommunication Company like AT&T or Vodafone or else ??? If yes, then your phone MNC/MCC had benn locked. For example :
- If your buy a phone in Europe which is bundling by Vodafone, then u cannot use it in America since it locked for Europe frequencies even the phone has global coverage frequencies but it's locked by that company.
But, as far as i know it included in ROM, so if you change your ROM with full flash then all the system and frequencies will be unlocked, just easy like that. And even your phone comes with bundling with specific country, actually it can't not use at all if your use it another country even for the 2G too, so when you use it say "Unknown Network" or "Network Unavailable" in the display, except your flash it with full flash.

Can u tell me what's your phone name and type that you say it that3G worked before you use this Xperia ???
I use Samsung Galaxy FIT and i can flash over and over again either thru flashtool (SAMSUNG flashtool named ODIN) or CWM, for a day now i've just reflash my Galaxy FIT with 12 ROM (7 Stock ROM and 5 Cutom ROM) with no problem with 3G Connection. In fact, Samsung has more simplicity in the software system. I've SK17i too, but since it's still have developer guaranted and i have this .62 firmware which must downgrade first to .58 then we can rooted so i'm leave it till my developer guarated expired then i'll install custom ROM too. Now plan to upgrade to ICS but Sony announced it'll decrease the performance, so i'll leave in GB for now.
Actually there's a software system which is involve for locking some frequencies for certain country, it calls MNC/MCC code --> http://en.wikipedia.org/wiki/Mobile_Network_Code.

The phone I had was a LG Optimus Me (p350) but i also had a xperia play (R800a) and the 3G was good. My girlfriend has a xperia 10 mini pro (U20i) unlocked by the company and she has no 3G if there is a way to get 3G here with this phones, bro that will be awesome!!!!

I think you don't know about telecommunication implementation. How come you can't get 3G with i-series ??? Have you red that phone specification ???. If u know about GSM and 3G implementation as ido (i work in these telecommunication field as an network engineer implementation). If you read that phone spec --> http://www.sonymobile.com/us/products/phones/xperia-mini-pro/specifications/ (see under Networks) you'll see :
GSM GPRS/EDGE 850, 900, 1800, 1900 so for 2G connection it cover all that frequncies that use in all over the world (except Japan, coz Japanese have different 2G and 3G network implementation) see this --> http://www.worldtimezone.com/gsm.html.
UMTS HSPA 900, 2100 (Global except Americas) so it means it cover all 3G frequencies that use outside America.
UMTS HSPA 800, 850, 1900, 2100 (Americas) so it means it cover all 3G frequencies that use inside America.
So why you're all saying that this phone didn't support you're country 3G, except you want to you use your phone in Japan, then it won't works as Japan use 3G with frequecies 1700/2100 MHz. The only possibility that i know is you're area was not coverage by 3G connection or even if that 3G had implemented in your country but it can't reach you're area so this what we called "Blank Spot" area. So please first get to know how the netrwork implemented in you're are, does it coverage by 3G or not.
For the code series, yeah you're right SK17i - it means for international release outside America and SK17a for inside America but it's not related to the frequencies coverage (notice these). SK17x or Xperia Mini Pro has globally working in all over the world that use 2G frequencies 850, 900, 1800, 1900 Mhz and 3G frequencies 800, 850, 900, 1900, 2100 MHz, except you're using it in Japan so it's useless.

You are mixing frequencies from sk17i and sk17a. In the same link you provide from Sony with the specs of MiniPro, there is a link to the white paper (pdf) and you can check that sk17i works with UMTS HSPA 900 (Band VIII), 2100 (Band I), and sk17a with UMTS HSPA 850 (Band V), 1900 (Band II), 2100 (Band I).
So, unless in America the provider was using 2100 band, the user wont get 3G connection with sk17i.

Refer to the white paper, so there's a different between SK17i and SK17. So thanks for correction.
Refer to this link --> http://www.worldtimezone.com/gsm.html <-- , I'm still had curiousity about the hardware, i've used to works as a phone technician in Nokia and Sony Ericsson for about 12 years ago, and you know in that time, different country has different GSM implementation (3G has not been implemented in that time, only GPRS). And sometimes i got outside job to flash another phone of my customer that they bought outside my country says like from Europe, Middle East or China and most of that phone was locked with their country origin Provider, and definitely can't use in my country, so i just flash that phone and sometimes i just only remove the MNC lock code so it can be use in my country. So i'm still curious why if we flash SK17i with SK17a ROM, and still it can't be used to connect to the 3G 1900.
it should actually be sufficent to flash your SK17i with the SK17a version using flashtool. as they are using the same modem chipset with just different frequency table.

Yes, i agree with you. Coz in 2000 - 2002 when i used to work as Phone Technician, i saw that the phone only have one component crystal for generating base frequencies, and yeah when we unlock a bundling phone or locked phone we just had to add some files that contains all the GSM frequency table, and then that phone can use in all over country in the world except for country that don't use global GSM frequencies like Japan.
But as inform by mr.daydu19 that he has just do that, and still he can't connect his SK17i which use SK17a ROM to the 3G 1900 America.
Can you provide a link to SK17x schematic diagram as i want to learn the hardware configuration.
Is it possible that maybe there's a hidden code/algorithm in the ROM SK17a so if u inject it to the SK17i then the ROM SK17a recognize that destination phone is SK17i, then it block again the 3G 1900 frequencies table files so we can't use that frequencies ?
Usually you will need to flash the entire FTF of a SK17a version which also includes the baseband, besides that the old x10's had a switch within the build.prop to decide which model it is and changed the frequencies if i remember correctly!
SK17a and SK17i UMTS Block
Now i attached schematic diagram from SK17i and SK17a.
You'll see that SK17a and SK17i has the same UMTS block named UMTS1 Band 1, UMTS Band 2 and UMTS Band 5, it's just on the SK17i at the UMTS Band 5 block it's using different chip with the SK17a. Here the list of the Chip on the UMTS Blok:
A. SK17i :
1) UMTS Band 5 block use chip SKY77705 which is an IC's for Band VIII --> http://www.skyworksinc.com/uploads/documents/201224a.pdf
2) UMTS Band 2 block use chip SKY77702 which is an IC's for Band II --> http://www.skyworksinc.com/uploads/documents/201217b.pdf
3) UMTS Band 1 block use chip SKY77701 which is an IC's for Band I --> http://www.skyworksinc.com/uploads/documents/201216a.pdf
B. SK17a :
1) UMTS Band 5 block use chip SKY77704 which is an IC's for Band V --> http://www.skyworksinc.com/uploads/documents/201222a.pdf
2) UMTS Band 2 block use chip SKY77702 which is an IC's for Band II --> http://www.skyworksinc.com/uploads/documents/201217b.pdf
3) UMTS Band 1 block use chip SKY77701 which is an IC's for Band I --> http://www.skyworksinc.com/uploads/documents/201216a.pdf
So SK17a and SK17i almost have same HARDWARE, the differential only at SK17a it works in three BAND 3G which is 850, 1900 and 2100, and SK17i works in 900, 1900, 2100. Good news is SK17i also has UMTS Band II block, means it can connect to 3G America with Band II which is 1900 MHz.
So if you full flash FTF SK17a to SK17i phone, it means your phone SK17i now can connect to 3G America 850 and 1900, but since the hardware only has 900, 1900 and 2100, so you can't connect to 850 coz it hardware was 900. But still you have 3G America 1900, and if you still can't get connection to 3G 1900 America in your country so i can be sure that your area was not cover by 3G Band II which is 1900 but your area was cover by 3G Band V which is 850 MHz, but since SK17i Band V block works as Band VIII, so it can't connect too. So, like i said before, please make sure what 3G Band that cover in your area and please post in here.

As in my previous post, so there's bad news, since you live in Nicaragua that only has 3G Band V 850 MHz, so it useless for you to fullflash FTF from i-series, since i-series only has 3G Band I - 900, II - 1900 and VIII - 2100 MHz in it's motherboard/module. So now u had to be notice for choosing phone that comes outside your country, even if you want to flashfull that phone.
Same as your girlfriend phone, it has hardware configuration like SK17i, even more bad news to this phone. Coz the schematic comes with only one for all (i mean it's not separate between U20i and U20a), so i can't be so sure if the 3G Band II - 1900 chip was exist for U20i too or it just 3G Band for U20a coz it's same schematic not separated. Even worse news is it comes with two hardware, one is with 3G Band II - 1900 and another with 3G Band IV - 1700. If your girlfriend phone maybe comes with 3G Band IV - 1700, so it's no other way you can get 3G in your country with this phone, but if it comes with 3G Band II - 1900 like SK17i, then u just have to wait till your country provide 3G Band II - 1900 and then u can flashfull FTF your phones.
Hope this helpful, and please take some research for your country 3G Band, what 3G Band has implemented ? and posting it here. Coz as far as i know Nicaragua only implemented 3G Band V - 850. But since you live there, maybe you can get update data.

I did a little research, and the company my phones is working with has a GSM 1900 with extended coverage, UTMS 850 MHz just for the city I'm at!!! so i guess that i can't use 3G :crying: is that so?

Hi. I have read all what u wrote guys (again sorry my english i can understand good but when i write am not so good) for a moment i thought that what u sed of unlocking frecuencys in sk17i was posible but i realise that yes there are diferent frecuencys in both phones.
am gona respond ur question and if am wrong someone to correct me.
U can flash sk17a rom in sk17i phone i heard a lot of people that do it. the only thing they do is save VPN configuration to conect to 3G network. but these phones came with frecuencys in hardware not in software modem driver mode like my samsung galaxy gt-s5830m that i can change mi modem with ODIN like u sed and rom to transform it in gt-s5830i (Indian model) so if a go to india y can use the 3g network no problem with that. So i think thats the problem with this sony ericsson models that frecuencys are in hardware. i read in taringa some user that said that with flashtool we can modify those frecuencys in the hardware to ad america´s. I send a private messege but he has not respond me. Well in htcmania spanish forum i olso asked but had the same respond that it was not posible and i will be always with EDGE conexion. but if someone have some news we will really appreciate that!!
In Colombia were i live i have

Unfortunately you can't use 3G Band V - 850 at this SK17i coz it's hardware only has 3G Band VIII - 900. This is details :
SK17a ROM has 3G frequency table :
1. 3G Band V - 850 ---> flash to SK17i that has chip for 3G Band VIII - 900 ---> so this 850 frequency table not work as hardware at 900. So you forget about this 3G Band V -850, it's useless for you if you wanna use this frequency to your SK17i.
2. 3G Band II - 1900 ---> flash to SK17i that has chip for 3G Band II (according to schematic diagram, it can be exist or not) ---> so this frequency table and hardware are matching so it'll work.
3. 3G Band I - 2100 ---> this of course match to SK17i, but since your living in America that's not implemented this frequency so forget about this frequncy too. But according to this link ---> http://www.worldtimezone.com/gsm.html some country in America has implemented this frequency too. So just take some research for what 3G Band your area covered.
Now, all we can rely is to the 3G Band II - 1900. I've just email some of my friends that still working as a technician in Sony to make sure that the 3G Band II - 1900 chips is exist in the SK17i motherboard/mainboard but still got no respons. But from my experience as a technician for about 16 years and since my school basic was in Tehcnical, if some component was not exist in BOARD but exist in SCHEMATIC so that component must be marking .or surrounding with "dash-line". And as you seen that our SK17i 3G Band II - 1900 chips was not marking or surrouding with "dash-line" so it's must be exist.

As my theory yes. Maybe you can try it and give result in this page. And make sure TIGO really works in 3G 1900 not two band, coz sometimes telecommunication provider expand their network by add another 3G Band but they not announced that as they don't have to. So this is what you've got to do:
As i used too works as customer service/front-desk from a providerGSM/3G card, you've come to one of TIGO customer representative office and asking if their GSM/3G card are works in 1900 only or two bands which is 850/1900 ??? If only 1900 then you don't have to changes/request to a new card. But if they card works in two band, then you have to request new card only works for 1900, as you wanna prove my theory if it's right or wrong. Coz if you put card that has two bands which is 850 and 1900, maybe your ROM can detect the 850 and it algorithm push only the 850 frequency table to works too, so the 1900 will not works. So just to make sure, please do as i say above.
