My friend recently updated his unlocked iphone 3GS to 4.3.1 and the insert sim to unlock message came up.
Only problem is he only just bought it and does not know whether it is the new/old 3gs or anything else about it.
I tried setting it to DFU and restoring to an older version to jailbreak but 3rd party firmware will only end up as errors when installing via itunes and official itunes updates are "not compatible" for some reason.
I also tried getting older itunes versions i.e. 8.2 and it says I cannot update iphone unless I have itunes 10.1. In addition to this I have tried jailbreaking with Redsn0w but also ended up in error, as I am not sure what version it is in. So basically at the moment I can either have it in 4.3.1 by updating on itunes or factory settings by setting to DFU and I cannot get past the sim unlock screen.
If anyone could help I would appreciate it, and im not just some idiot looking for someone to solve my problems for me as I have tried for countless hours to fix it but this 4.3.1 is giving me a complete headache.
Thanks.
