Can it be done and if so how?
Unlock is base on baseband. Do you know what firmware version & baseband on your phone?
One will be brand new. Howbdo findout the info. Not bothered about the jb apps just unlock.
If it's brand new then it will come with 4.3 or 4.2.1 and won't be able to be software unlocked. You could try that new turbosim to unlock it. It's around $70 I heard.
