Hi all,
I have a Sony Ericsson Xperia X10i, but it does not support (activated) HSPA 850 Mhz networks. Is it possible to activate this? I know that the Xperia X10a does support 850 Mhz. Is the 850Mhz HSPA option locked by software. If so, how can it be unlocked.
It's a really great phone. I already use this phone on 2G and want to switch to 3G.
Help please.
Winston
Unfortunately, like most cases of this, it is a hardware limitation. This is why they made two completely different models (X10a and X10i). It isn't just software that controls it, but it goes right down to the cellular radio in the phone itself.
Your best bet is to either switch to a network that supports the bands of the X10i (T-Mobile USA and Wind Mobile in Canada) or sell the device. I am sure some people who do use T-Mobile might be interested in the X10i as it works on that 3G network.
Thanks a lot for your quick reply. So now i know i don't have to research the internet for a solution. In my country Suriname, there is only one 3G provider, unfortunately on 850 Mhz).
This may be a stupid question, but can someone tell me what's the difference between R800i, R800a and R800x?

R800x is the CDMA Verizon Wireless USA variant, and is currently unrootable, but runs stock vanilla Android.
R800i is the original GSM variant sold over in Europe and the UK.
I'm not entirely sure about the R800a, my brain is giving me conflicting stories about Taiwan/Singapore, and Canada Rogers versions.... I could be ENTIRELY wrong on that though.
One is for verizon, one is for some other US network and the R800I is for the rest of the world i think
Models so far?;
r800i (uk, europe, australia, new zealand, asia?)
r800a (canada rogers, mexico + also asia?)
r800at (usa at&t)
r800x (usa verizon)
Z1i (china?)
They all have the same specs internal memory, processor e.t.c
In Mexico we get r800a too. With all the sony experience.
So the models depend on the location or the providers.

Both. In the case of U.S.A you guys get R800x for Verizon and R800at for At&T

I would say model depends on providers since anyone using gsm is likely to get the R800i or R800a anyone using cdma is gonna get the R800x or R800at.
The only difference in GSM and CDMA is gsm phones have a simcard, CDMA phones dont have simcards your account information is programmed onto your phone. Dunno if the CDMA xperia plays have R-UIM cards though? CDMA is supposed have have faster data transfer speeds (internet) up to 700kbps (EVDO). Gsm is roughly 400+kbps (HSDPA)
Gsm is world wide and CDMA is mainly usa and some parts of asia
I thought there was a dev model as well whats that one called?
Saw someone talking about it somewhere

The only difference between the R800a and R800i is the HSDPA radio frequency set. You can buy both in Australia as both frequency sets are in use by various carriers.
R800i works on 900MHz and 2100MHz
R800a works on 800MHz 850MHz, 1900MHz and 2100MHz
Firmware images are compatible between R800i and R800a.
Both are incompatible with R800x as far as I know.
I don't know about the R800at.

R800at isn't CDMA (its another GSM Variant). Interestingly, although it seems to do nothing and has a plastic bit inserted in the way, the CDMA (R800x) version does have a sim-card slot, and if you go into some of the diag screens, you can turn on GSM... I haven't tried getting a prepaid sim to see if it works though. So the R800x might just have both if we are lucky, however I doubt its fully enabled in the kernel level.
R800i is also Oceania ( AUS/NZ )

Thanks for the info. I was sure R800i & R800a are GSM and i knew R800x was CDMA wasnt sure about r800at so i just presumed it was CDMA as well
I cannot remember the post but i think someone has tried a sim card in the r800x and said that it has been fully disabled.
I'm in Singapore, R800i's here as well - nice thing about buying a phone here, all are carrier unlocked / government considers it illegal [monopoly] for carriers to sign exclusive deals... although I might get caned for exporting them.
Same here. No companies should be allowed to lock phones to their networks.
However some companies have been cheeky and released different phones that don't support the other carriers cell tower transmission.
I can confirm the R800at is the AT&T version. It even has the AT&T boot animation and comes loaded with 2.3.3.
I got mine in the mail today off ebay. So far, I am really enjoying it. I get H+ as my connection icon, and which is different.

You can root the Verizon model. If it is on anything higher than 2.3.3 you just have to flashtool back to 2.3.3 and then run super one click.

Im aussie too and the 800i is/was sold here for the optus/vodaphone network. You can use the 800i on telstra but you can only get 2g, no 3g goodness due to the frequencys used.
Does the network frequency of Arc fit T-mobile? I can use 3G in China, but only GPRS available here in America with T-mobile network.
Anyone can help me?
Thanks
What is your phone code number, in America it is Lt15a, a is American, if you use i, this can be a problem maybe, they have different frequence like you said, first you can ask this to Sony Ericsson i guess?
Hi everyone,
It's always been known that there is a 900/2100 Defy and an 850/1900 Defy.
I got mine from my 850mhz carrier in Australia. I am visiting Hong Kong at the moment. I purchased a one2free SIM (900mhz network), changed my baseband, and got on data with full HSPDA! I can download around 200kbytes a second.
Thought I'd share for fellow travellers.

Hi, how did you change the basebands to HDSPA 850/1900?
Look up "baseband switcher for defy" in Google. You'll be surprised. It's not really news...
Thanks for your answer, but I have a Defy+ with cm7. I tried with basebandswitcher and baseband of cyanogen but didn't work, they didn't change frequencies and the phone lost signal. Do you know why? Thanks
Hey jsut wondering if anybody on this site is in the Ontario area and where they got their phone + when..
I cant seem to find an xperia play that works on local frequencies.
I recently received the one i ordered off Amazon. But it is not accepting my SIM, it cant even be unlocked cuz its an international phone..
Is there anything I can DO?
These are the frecuencies supported by Xperia Play in its GSM version:
GSM GPRS/EDGE 850, 900, 1800, 1900
UMTS HSPA 900, 2100 (Global except Americas)
UMTS HSPA 800, 850, 1900, 2100 (Americas)
Probably the UMTS frecuencies for America are supported by the R800a and the other ones by the R800i.
If you need a R800a and you have a R800i maybe you can flash a R800a rom to modify the supported frecuencies. Search this issue in the forum, you could find something about it.
Try flashing the R800a firmware and see if the phone will accept the card. Otherwise you are out of luck. Should have bought an R800a from rogers and simply unlock it.
I dont think this will work as an R800a can flash an R800i firmware and the frequencies still run on the R800a frequencies.
Edit: I bought my phone off someone from Kijiji for $200 a year and a half ago. It was locked to Rogers. I bought an unlock code for it and unlocked it. Then put in my Bell SIM card and input the Bell APN for data/MMS. Then I got my bootloader unlocked. So I am using a Rogers R800a, with a Bell SIM running MIUI v2.9.21 r1 from cosmic DAN.
