If I buy a new iPhone 3GS on eBay, can I transfer the SIM card from my current iPhone 3GS into the new one and will it still work?
I have an 8GB iPhone 3GS on AT&T, and I wanted to purchase a 16GB version on eBay. Will I be able to just pop the SIM card out of the current iPhone 3GS into the new iPhone 3GS and have it work properly?
