use even use it! PLEASE HELP? So I literally just updated my unlocked iphone with the new software and now iTunes says:
The SIM card inserted in this iphone does not appear to be supported.

All I can do is make emergency calls and I need my phone back ASAP.

Is there any possible way to undo the last software update?


I had cydia on my phone and stuff, if that helps...
PLEASE any info, ideas would be appreciated, thanks!!
Oh and its a 2G iPhone if that helps.
