I have just updated my phone to the new 4.01 software with games centre etc and im wondering how i can jailbreak it or unlock my I phone 3gs so i can use my 3 sim card on it if anybody knows how or has the software
Since 4.0.1 doesnt have game center I am assuming you mean 4.1. If you indeed upgraded to 4.1, then you will not be able to unlock. You can use Greenpois0n to jailbreak, but before you do, can you doublecheck your firmware version and modem firmware version in the about section of your general settings... Thanks.
