Hi there, thanks to 'uqbah' and this sounds like it works. This is the third time i returned iPhone for replacement at Apple store. However screen is on 'Different sim detected'.
I have a 3GS 3.1.3 MC model on Orange
I got this new one 2 hours ago, just got home and this is what i done>
Activated phone with Orange sim
Jailbroke using Spirit
Installed source: http/repo666.ultrasn0w.com
Installed: Ultrasn0w
Installed: SSH
Now i followed the steps exactly and now when i put tmobile sim i have network whereas before i never, so thanks for that BUT iPhone still stuck on that screen and i can receive calls.
Permissions set as 0644
Could you help and tell me if i done wrong? Thanks
