I am getting an unable to load network error on my iPhone once I jailbrake it. It is running on OS 4.1. and the modem firmware is 05.14.02. Any ideas on what can help?
You only jailbroke or 'hacked'. You have to unlock to be able to use it on T-Mobile.
And baseband 05.14.02 is not unlockable. The only way to unlock it is to flash the iPad baseband onto it, but I feel like that might be over your head.
I already have one iphone working on t-mobile. It is working greate. I tried to to this with ultrasn0w and that is when it happened. is there a write up on here on how to do it.
