iPhone 3gs wont update from 4.2.1 to latest update
I have got a iphone 3gs myself which is on the latest update but I have tried to do my girlfriends which we have only gotten unlock from the telstra network in Australia and it tells me that the 4.2.1 version is current version. This phone hasnt been jailbroken therefore im at a lost for why i cant update it. Anyone that cant shed light on this would be great.
Thanks in advance,
