Hi,

I was on 4.01 and updated to the latest version of ultrasn0w from cydia (1.2 I think). All was fine until a few days later I had to restart the phone. First it took ages to boot and then when it finally did it was showing no signal.

I took out the sim and popped it back in and this error message comes up saying "Sim Failure". Upon connection to Itunes it displayed a message saying that the sim was unauthorized. Uninstalling and reinstalling ultrasn0w didn't do anything.

Then I restored the OS to 4.2.1 and tried again with the latest version of ultrasn0w and the same thing happened. Now I'm back on 4.01 with ultrasn0w 0.93 and so far the phone seems to be working fine.

Any ideas on what's going on? Anybody else experiencing this issue?

Thanks!
