I just stumbled across this old thread.
http://forum.xda-developers.com/showthread.php?t=265606
Is the possibility of this true?? Has anyone tried to do work on the Radio ROM to bring in Quad band? I would pay to have 850 available for my phone.
Comments?
Has anyone tried an Athena radio on the Universal ( I presume yes, still looking through the forums ). And what about the HTC Sable? They both use the same CPU and the Sable in particular has comparable ROM sizes.
Quote from one of the links:
QUALCOMM's MSM6250 chipset solution helps enable worldwide roaming for
WCDMA (UMTS) terminals. The MSM6250 system solution supports dual-mode, quad-
band GSM transceiver operations [GSM 850, GSM 900, Digital Cellular System
(DCS) 1800, and GSM 1900] and WCDMA (UMTS) transmit operations for 800 MHz,
1900 MHz and 2100 MHz.
Shouldn't the Universal therefore be able to do 850 with a change to the radio ROM? Do the HTC Sable and Athena use the same chipset?
Can anyone help us?
It would be great to have a 850 band for my SPVm5000. Hope anybody can answer your question. Seems that since this phone was only released for europe and not USA the quadband was not open
What is the difference between the Touch Diamond sold in Europe and the ones sold in US?
And the ones sold in Brazil (TIM and Claro operators using 850 Mhz 3G band)?
Which ROMs the Brazilian operators (TIM and Claro) use in their 3G 850 Mhz Touch Diamonds?
Is it possible to make European Diamond (France) operate in 850 Mhz 3G band?
As far as I remember after reading on this forum, unfortunatly no.
In the development thread DooMLoRD mentioned that the phone comes in two versions. There seems to be confilicting info about this. I have seen sites say it is quad band HSDPA and there is not 2 different models and only the lt26i. I would like to import to the USA and use on ATT 3g. It looks like the lt26i will work on att 3g. Below is the info listed in the development section of the site.
Model number:
The Xperia S has model number as LT26 and has two models LT26i and LT26a. They differ in the spectrum of frequencies supported for 3G/WCDMA http://www.gsmarena.com/sony_xperia_s-4369.php
LT26i - HSDPA 900 / 2100
LT26a - HSDPA 850 / 1900 / 2100
The items passing the fcc was the LT26i and it was listed at quad band UMTS/HSDPA

It is also mentioned in this engadget article
http://www.engadget.com/2012/01/27/sony-xperia-s-jogs-past-the-fcc-carrying-plenty-of-atandt-t-mobi/
I've pre-ordered the Xperia S LT26i from here. If you scroll down a bit and switch to the specification tab you'll see this:
GSM/GPRS Yes
Frequencies 850/900/1800/1900 MHz
Speed GPRS up to 86kbps, EDGE up to 237 kbps
3G/HSPA Yes
Frequencies 850/900/1900/2100 MHz
Speed HSDPA Up to 14.4Mbps, HSUPA Up to 5.8Mbps

It seems like it supports both frequencies... It'll surly work in Europe right? I live in Israel using Cellcom, I hope it'll work fine.
I am wondering the same thing too!
I live in Canada and I want to get this phone but I know Canada will be the last to get it.
Is the ' i ' version going to work for me in Canada?
Please help!
Thank you.
check the Xperia S whitepaper
http://dl-www.sonymobile.com/cws/download/1/105/035/2/1327908899/Xperia_S_WP_2.pdf
"LT26i UMTS HSPA 850 (Band V), 900 (Band VIII), 1900 (Band II),
2100 (Band I)
GSM GPRS/EDGE 850, 900, 1800, 1900"
so it's safe to say there is going to be only one version?
if so, I will order my Xperia S and start using it in Canada!!
From what I have seen for the last three months, only one version which is quad band. Today I ordered one from ebay shipping from Hong Kong and I should be receiving it next week sometimes around Thursday. I will report back once I have it.
EDIT:
for people interested, this is the place I ordered it from http://www.ebay.com/itm/Sony-Ericsson-Xperia-S-LT26i-Unlocked-12mp-32GB-Android-Phone-White?item=150770279921&cmd=ViewItem&_trksid=p5197.m185&_trkparms=algo%3DRPSI%252BSIC.NPJS%26itu%3DUCP%252BUA%252BMAGEXP%252BI%26otn%3D12%26pmod%3D190644185862%26po%3DLPV%252BLVI%26ps%3D63%26clkid%3D6745036511139896139#ht_3032wt_1396

This.
White paper clearly states HSPA 850/1900 is included. And FWIW GSMArena corrected the specifications page to reflect this http://www.gsmarena.com/sony_xperia_s-4369.php

I have ordered one from Clove in the UK. It should be shipped Mon or Tue.
I will report back once I either trim down my SIM card or buy a micro SIM.
I am on Telus now running an unlocked generic Xperia Arc.
Cheers
I can confirm it is a quad band. It supports UMTS/HSPA Bands 1/2/5/8. See screenshot from my service menu.
PS: the phone is unbelievably awesome.
I know this thread is old.. but my xperia s only gets edge internet conection..! D: No 3g at all! I'm in Bolivia btw. With "a" versions of other xperia phones I was able to get 3g internet connection.. why is this happening?
The 'a' and the'i' signify different versions of Baseband. The baseband determines which 3g network you connect to ! Make sure you pick up the right instrument otherwise you wont be able to connect to 3G. Google "3G baseband" + your Country and then see which model, the a or the i supports that baseband Wrong baseband => No 3g
Hi,
I was wondering if I would have any limitations using a ATT / Rogers phone in Europe (Austria)?
What worries me a bit is the different model numbers and specs (RM-808 in US/CAN vs. RM-823).
Seems HSDPA is not supported on 900Mhz in the RM-808 and according to the Rogers website their Lumia 900 does not support HSDPA on 2100Mhz either whereas ATT's Lumia 900 supports HSDPA on 2100Mhz.
gsmarena RM-808
gsmarena RM-823
Rogers Spec
ATT Spec
sorry I can't post the links as a new member
I then found a old posting telling a bit about the used frequencies for HSDPA
Europe: 2100 MHz, England 2100, 900 MHz
Asia: 2100 MHz
Australia: 2100,850 MHz
America: 850, 1700,1900 MHz
So if that is right I guess the Rogers Lumia 900 will not work on European HSDPA networks (only on the 2G)?
Or is the Rogers website just missing this detail as the model number is the same so the hardware should be identical?
I don't care to much about HSDPA 21 or 42 Mbps as there might not be a huge difference in every day use as the networks do not provide anything close to the theoretical speed.
I'm looking to buy a HTC One M8 T-Mobile version, and unlocking it.
I read on gsmarena.com that the frequencies that work on that phone are these.
GSM 850 / 900 / 1800 / 1900
HSDPA 850 / 1700 / 1900 / 2100 - T-Mobile
LTE band 4(1700/2100), 17(700) - T-Mobile
Now the frequencies in my country are
HSDPA 850 / 900/ 2100
LTE band 4 1800
If I unlock the phone will it be open from my LTE frequency in my country, and the 900Mhz 3g in my country,
or are the phones made for T-Mobile only work with those frequencies no matter if you unlock it or not.
Thanks in advance for all answers!

Unlocking it will not add or remove any of the phones frequency or protocol items.
Unlocking merely allows the device to use another sim card from a carrier that it was not branded for.
So if its a TMO branded unit and you unlock it you get all the features that TMO asked HTC to make the unit for them for, but you can use it with your carrier.
