I was planning to buy another 16 GB phone today, and AT&T is closer to me than Apple. However, does AT&T make you do credit checks before you walk out the door still? I don't want to get my credit check hit again, since I already have an AT&T account and everything. Does anyone know if they still make you do that? Also, do most AT&T stores appear to have the 16 GB version now? Thanks.
