Thread: not authorized sim
10-16-2010, 03:54 PM #1not authorized sim
I jailbroke my 4.0.2 and unlocked it for t-mobile last week while the limera1n came out. Weird thing happened this morning. When I turned on my ip4, a message 'Invalid sim" appeared on my screen. However, after I rebooted a few times, the t-mobile came back. Is there anyone know what was happening on my phone?
I spent more time on this issue. And I think it's because the t-mobile signal is not that strong at my home. And I turned on my phone in my office last couple days. My conclusion is I will still have this problem if I turn on the phone at home. Once it gets t-mobile initial signal, the phone would have no problem for whole day until you turn it off.

Did you cut the sim card by hand?
