The sim card will cost... Ask ATT for the price.
I recently replaced my iPhone 3GS with an iPhone 4, but want to give the 3GS to a friend to use as an iTouch. I accidently lost the SIM card and tray, restored the 3GS, and now it wants a SIM card. Can I buy another tray and a AT&T unactivated SIM card, and get it to at least go to the home screen?
