I would like to know how many differences there are between this two kind of dual band.
i've bought a T-mobile from USA (i'm still waiting for it so i don't have it now) and i saw that it is a 900/1900. I'm in italy, so i would like to know if i'll use only 900 or 1900 too (i think in italy 1800 is used).
i think i'll have to unlock it, the vendor told me it is a pocket pc 2003, do XDAunlock, work on it?
(i'm sorry for the last off topic question...i post here to not make too many post around the forum)

I'm sorry to tell you since your network works on 1800 Mhz your new T-mobile PW10B1 wont work on this frequency it's made for 900/1900 Mhz if you unlocked it or not it's not gona work, you need the PW10A1 devices they work on 900/1800 Mhz.
but there are cellphone companies in eu who use 900 maybe there are some in your country
if not well thats too bad
oh....no..... :shock:
is there anithing i can do? radio update??? something like this!
Your special edition ROM can help me?
from what i've been able to understand about the 900/1900 then it's a hardware limit the GSM part of the xda1 will have to be physically removed which would most likely be way more expensive then getting a new device
of cause i could be wrong
The XDA1 is available in two flavours (from what I read):
USA: 900/1900 bands
EU: 900/1800 bands
Since both flavours support the 900 band, you should be able to use it in Europ on one of the 'old' networks.
In Holland both KPN and Vodafone have nationwide coverage on 900MHz.
Since TIM is and 'old' company too (Telecom Italia isnt it?) I guess theyre on 900 too. To be sure: check the websites of the Italian mobile operators. Be aware that reception in some areas might be less than if you could use both 900 and 1800 bands as more and more operators are extending their networks on 1800 only (because of lack of free 900 band frequencies). I noticed this a few years back in France where in rural areas there was no coverage with a 900 phone and full reception with a 900/1800 phone (same network).
Reading the forum i've read that is possible to chose band 900/1800 and 900/1900 by bootloader and pressing calendar...can this be true for some model?
p.s. Of course TIM uses 900...i wonder if it will ever use 1900 one day
i think UTMS or some other replacement will take over before us and eu start to use the std's of eachother
just another question, i found information about special edition rom. It says that with bandswitch.exe some devices may work with other "not natural" band. So i'll try when my XDA will be shipped.
TIM wil NEVER use 1900, at least not in Europe. The 1900 band is not available for telecoms in Europe (just like the 1800 band is not available in USA)
I've got T-Mobile from US working in Russia on 800/1800 through ROM upgrade. What it did - it removed SIM Lock and turned the device into 3-band. Works perfect.

i haver never heard about anybody being able to make a dualband into a triband using just software the filters and mixers in the hardware part og the gsm are different
I have never heard about that either. As far as I know frequencies are hardware based. Otherwise we could flash our XDA's to anything we wanted.
I have researched this for weeks and weeks since I need my XDA I to work on the 850Mhz network in the US quite badly.
Please post exactly how you did it
1800/1900
I got the same problem you do but reverse , I'm in the U.S and bought the phone from Europe ( qtek 1010 ) my phone will not work in the U.S because the network here is 1900 and in europe 1800. If you want I can trade with you if you have the same phone. I got all the package in a box.

There are 3 major networks in Italy that have 900 mhz networks.
They are:
Telecom Italia Mobile (TIM)
GSM 900/1800
Vodafone Omnitel N.V.
GSM 900/1800
Wind Telecomunicazioni SpA
GSM 900/1800
If you are within any of their networks you should have service with your
current Wallaby. (XDAI). You should be able to insert your sim card and go.
Some ROMS auto select the available network, others do not. There is also a program that you can cook into a ROM that give you a software selctable band switch.
I hope this helps?
Joe
Just to clarify my last post:
It has been discussed on this forum, for a few years, that you cannot
change a 900/1900 phone to 900/1800 using software.
However since your phone does operate on 900 mhz and there are
900 mhz throughout Italy, including Sardinia, you should have no problem using your current phone. In fact I have used my USA 900/1900) XDAI in Italy.
Let us know how you make out.

900/1900 T-Mobile -- Swap for an 900/1800 XDA ?
Straight swap...I made a mistake and bought a T-Mobile from the US thinking it would work in NZ....it won't and everyone on the forums agrees....so only option is to replace with a European one...
If anyone is interested, post a reply and we can set something up.
Cheers, Hamish
BandSwitching
I live in Jamaica, we have to GSM networks, 850/1900 & 900/1800 my XDA1 works well on both networks... although signal strength from the 900/1800 is stronger it makes no big difference... I believe the shorter band is essential in buildings etc. so wait till you get the phone and give it a try.
I tried the Band Switching application in the Special Edition ROM, it made no real difference.
Slightly off topic can someone point me to an explanation of UMTS???
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.

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

I recently switched to Mobilicity from Rogers...but the irony is that I can't use my lovely X10 on Mobilicity. Mine is X10a, and I recently flashed it to X10i (although I didn't know it will switch to X10i, but it did) using forum.xda-developers.com/showthread.php?t=825201 tutorial.
Ok, the big question is that can I somehow manage my X10 to work on the frequency Mobilicity is providing. Following are the lines from wikipedia.
"Mobilicity uses the UMTS IV frequency band, also known as AWS, to provide UMTS (with HSPA) service.[11] Using this band, user equipment transmits at 1710–1755 MHz, and receives at 2110–2155 MHz. This is the same frequency as Wind Mobile and Videotron in Canada and T-Mobile USA. Like WIND, they do not have a GSM network."
"The Xperia X10i uses GSM/GPRS/EDGE 850/900/1800/1900 and UMTS/HSPA 900/1700/2100. The Xperia X10a uses GSM/GPRS/EDGE 850/900/1800/1900 and UMTS/HSPA 800/850/1900/2100."
Please be easy on me as I am a newbie

the carrier is not going to change the frequency for you.. As it looks Videotron and Mobli will survive Wind took a hard hit just today. The CRTC and Industry Canada are getting pressure to reopen the ownership debate. If that falls though Rogers will add data to chat-r and seal the fate of Wind. Then you can simply switch over and be fine.

ok, I will wait for a month or so. I guess North American handsets always had problems. I remember I took couple of handsets to South Asia 5 years ago and they werent working there, but their handsets worked in North America.
Btw, my current plan is 35+tax and it includes.
Unlimited Incoming & Outgoing
Unlimited Text (Global and domestic included)
Unlimited Long Distance for North America
Unlimited Data
Caller ID, Call waiting, Voicemail, Call Forward, 3 way calling
I doubt Rogers or its subsidaries can offer such a plan.
Btw, I am a webdeveloper who wants to get into mobile development scence as well. Any guidance will be appreciated as I am a complete newbie when it comes to mobile development.
It is funny to tell but my x10a is not working the right way
The 3G working bands are as the service menu says:
umts_bc1, umts_bc4, umts_bc8
instead of
umts_bc1, umts_bc2, umts_bc5, umts_bc6
So I can't use the 3G anymore that's because in my country none operator uses the bands that my phone has, It seems my x10a phone uses x10i bands now.
Hello,
A month ago I bought an X10i mini from a private local dealer, and after a while I discovered that my provider (Pelephone in Israel) is using the American frequencies (HSPA 850 and 2100) while the other 2 local providers (Cellcom and Orange) are using European frequencies (UMTS 900 and HSPA 2100).
This means that the suitable model for me is X10a and not X10i.
Today I can use the phone (upgraded to latest 2.1 release with SEUS and then root-ed it with SuperOneClick), but I have many reception difficulties for indoor use because only the 2100 frequency is working with my phone and not also the 850, which gives better backup reception inside buildings and in challenging topographic areas.
I tried the special code trick mentioned here:
http://forum.xda-developers.com/showpost.php?p=10645063&postcount=16
I did get a special menu but without the Radio Selection option.
Are the X10i mini and X10a mini hardware different, or is it only a matter of ROM changing/debranding? Maybe there is another special code for changing the frequencies?
I need to know if I have to do a physical trade of my X10i mini with X10a mini, or can I just enable the American frequencies in my X10i mini.
Thanks!
wrong forum.... try the x10 mini forum
Sorry about that. Will post another thread in the correct one.

It is actually no difrent bro, I'm from Nicaragua and i already tried that, but it is a hardwere problem, the sk17i means that the phone is international type, and sk17a is for america. so unfortunately u can't change that, we will never have 3G with i Series :crying::crying::crying:
Are u really sure? bicause i have a samsung galaxy ace gts5830m and i can change kernel, rom and modem to other version to change 3g frecuency. am asking if ur very sure bicause suddenly u dident flash all ! only rom or well i really dont know how is in sony ericsson phones. but in galaxy u can flash only one. To change only one thing.

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.

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
COMCEL NOW CLARO MOVIL
GSM: 850MHz
UMTS/HSDPA: 850Mhz
MOVISTAR
GSM: 850MHz
UMTS/HSDPA: 850Mhz
TIGO
GSM: 1900MHz
UMTS/HSDPA: 1900MHz
Am claro movil so if i use tigo i can have 3G conection with 1900 frecuency in sk17i

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.
