Hi, O2 UK will unlock it for free if you are on contract and have had an O2 sim in it for more than 24hours and been with them for 3 months.
If you are on Pay as you go, then it will cost you a £15 top up before you request it.

Can anyone please answer my question about my serial? am i correct to say that my phone was made in 2011 and the 22nd week?
so that would make me in the clear to install ipad baseband and then downgrade it to unlock my phone?

For those who are wondering if you can update your 3G or 3GS to 06.15 solely for the purposes of downgrading to 05.13.04, the answer is “yes” for 3G owners, and “maybe” for 3GS owners. The iPad baseband is not compatible with 3GS units manufactured week 34 of 2011 or later. If you have an iPhone3GS and if digits 3-5 of its Serial Number are 134 or later (xx134…), then you should NOT try to install the 06.15 baseband on your 3GS! It will brick your radio, preventing both the downgrade from working and normal iPhone software from using it as a phone! Be warned!
Yours is xx122 so I read it as being week 22 of 2011 so you should be ok.

Hi, it looks like it to me. I think that the 06.15 baseband caused problems with GPS so that is why you upgrade to 6.15 first and then back down to 05.13.04

Serial number starts with QR means it's a refurbish iPhone from Apple. You can't use the first 5 digits to determine the bootrom line an original iPhone. Be extremely careful about using Redsn0w to change baseband. If it's a newer model with a Toshiba chipset, you will wipe out the baseband info and render it useless as a phone (can only use it as an iPod).
iH8sn0w has iDetector to verify if the baseband is flashable or not ... You can check out his blog at:

Don't try, you will brick your iPhone. As it's 3GS 8GB model (must be newer than required models).Contact me to "factory unlock" any iPhone!
