Hello all! Long time MacRumors.com reader... FIRST time poster on here. Just wondering about some purchasing options for a Christmas gift for my girl. I want to get her an iPhone but don't know where to start. She has AT&T (Cingular phone and GSM Chip) and I want to know what type of phone to look out for. Unlocked? AT&T only? Used? New? Just buy it from AT&T? Where should I start? I would ideally want it to be "drag and drop" with her current SIM Card. I do know that she would have to activate the iPhone data plan though so she can take advantage of all the features. Help! Thanks... 4Life!
