A coworker of mine just bought an Xperia X10a and is off the Germany for work she sent me a txt asking me to get her the unlock code and also to tell her if it will work in 3G while in Germany.. from what I can tell from the specs I think so.. but I thought best to ask the experts here. I know there is a X10a and a X10i I need to know if her X10a will get her 3G in Germany before I get the unlock code.
*edit* code is 6.00 is it would not be a total loss if it did not work..
thanks
So no one knows? or was it a silly q?
I don't know what services are available in Germany or what firmware you are putting on, but if it is available, it should still work. Debranding and unlocking don't take away the capability as long as it was available in that firmware and service is available in your area.

thank you.. I was hoping to hear that! I know my k850i was able to get 3g in Germany Italy and France.. so I was hoping her xperia x10 would be fine.
You need to have carrier frequencies to use the 3G. has nothing to do with the firmware but only the hardware.
10a are on 850/1900 and 10i on 900/1700/2100

That's right, 3G on the X10a won't work in Europe, or most of the rest of the world.
A little rant: Why do the US insist on always changing something instead of using the international standard? I can see no advantage in that to either their citizens or foreign travelers that visit the US. Just to mention a few: only 3 countries in the world don't use the metric system (US, Liberia and Myanmar), the cellphone bands are standard pretty much everywhere else, most countries have 220v energy (though the plugs vary in format you don't need a transformer). It's a bit like the English driving on the left side. It benefits no one.

Yes, it will on 2100. Very few countries in Europe and Asia have the 900 or 1700 3G bands and definitely not exclusively, they all have 2100 3G.

The other thing your friend will need to check is that they have international data roaming available and also a LARGE bank account lol
She has my vodafone sim so roaming is not a problem. She is at a spa for the weekend so I can not report back but AFAIK it should be fine. I think she may want it debranded so i am thinking to debrand mine and just ship it to her as she will be there for a while. yeah I am good like that! So the consensus is it will work just fine?!

Yes, I believe so.
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.
The Atrix can't use 4G on tmobile.
Can the new roms with the unlocked bootloader change the radio frequencies to work with tmobile's network?
or
Is this a hardware problem?
No unfortunately it is a hardware limitation.

Are we sure it is hardware? The specs say qualcomm mdm6200 which via software (as per the qualcomm data sheets) is able to use umts 1700/2100 bands(ie AWS bands).
Let me grab the links.

I was reading the pin outs and that is where I determined that there are no seperate pins for AWS or well any band and so I would assume the frequency is baseband determined.
If anyone is still looking. Pages 102 through 104 is interesting as it gives the pin outs that need to be programed in software for the correct bands. If anyone knows how to break open a radio firmware or program the radio that would allow us to get all bands working I think. This would also possibly allow for targeted radios that use less energy since they only rx/TX on the frequency that is available in that location.

Just like on the Samsung Infuse 4G, ATT's radio on the SGSII restricts the band selection\alternate carrier selection when using different SIMs .... are there any radios yet that can be flashed to disable this limitation yet? Flying to Asia tomorrow so would be nice to have the ability.
As far as I knew it has nothing to do with the Carrier software (at least it doesn't with non-android phones I have. They have a manual selection menu hidden, it's just the SIM locks it down.

Well if a sim locks it down that's a carrier restriction
If all you want is Sim unlock, get your Sim unlock code. ROM or modem won't make that happen.
There are a few ways to unlock your phone. Do a search.

Not to be rude but there's more to it than that... I travel internationally weekly and you're correct when it comes to using country specific Sims in thosecountries bit not when it comes to using a "country x" sim in "country z" on an att phone. I went through this with infuse too and flashing Rogers radio solves the issue. Its an att imposed limitation.

That is because if you are using AT&T Sim, there is a built in preferred carrier list from
AT&T to keep the cost down, to At&t, not necessary to you.
IIRC, if you Sim unlock and use a local Sim, you will have the option to manually select network.

Known as a PRL (preferred roaming list) but this does not effect the ability to use a different SIM. The PRL is on the SIM not on the phone. Typically, you have the option on the device to ignore the PRL and do a manual network selection but only if the subsidy lock allows it.

You should be able to remove the subsidy lock without having to change the modem firmware. As for the band selection, a modem from the international version of SGSII is probably your best bet. But do a search to see what happens when applying different modems for overseas use.

Yeah, that's the issue is I need to be able to select a carrier. The phone is sim unlocked, but it's preferring a different carrier than I need to be using. Any way to free myself from being able to get the international version? Won't the International version not have the appropriate "4G" AT&T frequency\technology?
Thanks!
As a side note, I'm in Bangkok at the moment. I just grabbed a dtac one day sim (cause using local sims work, it's just when using foreign roaming sims i have the att issue selecting a carrier manually), and whatever category of HSPA+ they're using is rockin no a mofo... I'm getting 11mbps down and 2.44mbps upload. Now THAT seems more like "4G" than anything we have back home in the US, hehe.

Not true, on the Infuse and this phone, it's ATT's radio that prevents manual selection of networks. If you take an infuse, and unlock, then try to manually select a network operator, the menu is grayed out. If you then flash the rogers radio, wa=lahh... the network selection is available.
Yea, this restriction has nothing to do with the SIM. It's the AT&T-customized radio that's in our phones. The AT&T Android also removes the 3g/2g toggle, but that has nothing to do with the radio, and is a simple Android tweak.
I think we're gonna have to wait and see if an I9100 modem will work with our GS2s and if it will support both 850 Mhz and 1900 Mhz WCDMA...

Yeah. I'm finding that it's not a huge deal anyhow w\ Google Voice. More and more while travelling I want to use my phone for internet, and thats never cost effective for using a global roaming sim like Tru anyhow. Here DTAC, the biggest carrier just turned on "4G" (funny enough they call it 4G+ haha), and I'm getting 10mbps+ down and 2.5mbps+ upload. It's crazy-fast compared to my ATT at home. And for 30 Thai Baht per 24 hours it's unlimited data and unlimited local calls. Can't beat that. Here until Friday, so for $5 I have a week of amazingly fast internet.
Question for you. Does the International unlocked version have the ability to use the same HSPA+ frequencies and work fine on ATT? I like that idea if it does, seems a lot more people developing for it. But I'm not sure I can give up having 4 capacitive touch keys having had them for 2 phones now, hehe. A physical button just looks so old-fashioned, hehe.
Thanks!

International version of GS2 has quad-band HSPA+ radio (supports all AT&T bands w/o problems) while AT&T GS2 has only tri-band HSPA+. If you travel a lot internationally and want local 3G/4G data speed, international vesion is a better choice.

That may not be the case.
The Captivate had a published "tri-band UMTS radio w/ 850/1900/2100" support, but in reality the radio supported 850/900/1900/2100. Suspect it's the same case with the SGH-i777. Further, the potentially missing UMTS/WCDMA band (900 MHz) is used in very few places, and almost no where exclusively.
But back on topic:
When I have some more time and feel like mucking around, I might run through a bunch of different i9100 modems and see what happens.

This same thing is true with the i777. And turning on the 900MHz band is done with the same method. Not sure if it will stick though.

SK17i type phones have 3G chip, that only uses specific bands, SK17a type phones another type chip.
You can't change that. If your shop sold this, you might go back to the shop and explain to them, they should change it for you, if it doesn't work in their region.

The frequencies cannot be changed. If the phone is set to work on these frequencies, it will work so.
Phone, which is made to work on 900/2100 Mhz, cannot work in 850 Mhz area, because the chip hasn't been built so.
