I purchased a new iphone 3gs 16 gig, i was in the process of unlocking it.., but found that there are no solutions for Iphone 3GS with firmware 3.1.3 BB 05.12.01.
Tried very hard on google for a possible solution but could not find one.
I am very new to iphone unlocking.., but understands all methods.
Can anyone help me if there is any possible solution to unlock my iphone without downgrading it.
You have 2 options. 1 - wait until iPhone OS 4.0 comes out as that is the next version that will be unlocked. 2 - Sell your phone and buy one that has not been updated yet.
OS 4.0 is not scheduled to be released until late June or early July. After this the baseband will be final and the Devs will get started on a new unlock.
