i am facing the same problem that the user "atm" was having

I have an iPhone 3GS (AT&T). It was unlocked/jailbroken, & I've had Straight Talk running for a few weeks now on an older iOS.

Today I upgraded to iOS 6 & now I can't use the phone because I'm stuck at the activation screen. After following the screen instructions, I eventually get to a screen titled "SIM Not Valid". Below reads:

"Only compatible SIM cards from a supported carrier may be used to activate iPhone. Please insert the SIM card that came with your iPhone or visit a supported carrier's store to receive a replacement SIM card."

Please can you help me out

I have a new iphone 3gs and upgraded to iOS 6 on the first day and now I can't get past the activation screen and I can't get iTunes to recognize the phone. I also can't change the APN setting via iPhone Configuration Utility. Help please.

I have an iphone 3GS and am stuck at the activation screen as well after upgrading to ios6. I can't use configuration utility to update the APN either. Need help please.

same issue. sim card not valid. tried everything. asks for original sim. itunes says not compatible. iOS 6.1.3. tried restore through itunes with no sim, tried redsn0w jailbreak and it freezes(guessing cuz I don't have the ipsw to give to redsn0w to identify the 6.3 update).
