activating iphone without atnt sim card (iOS 5)

[tthjs]

So, i bought my phone unlocked and had it for a while then recently it stopped working properly so i updated the software using itunes. the update completed but they are saying i need a sim card (without a PIN code) from the carrier (im guessing atnt) to activate it. i did the update yesterday so it would hav updated to 5.0.1 i guess.
what should i do since i dont have an atnt sim?
i cant do anything with it right now
