Hi,

thanks for this promising info (non-AT&T iPhone supported on AT&T network now). So I'd think the best (and only) way to get this working is to walk into one of their stores and buy one of these 25$ data plus 25$ phone plans for one months. Since I will be in the U.S. for three weeks this seems perfect, and 1 GB of data is also the right data plan.

Does anyone know whether this plan allows a) Tethering and b) VoIP calls? Or is there an additional option I'd have to buy? Heck, why is this AT&T website so intransparent and confusing (OK, others are not better...)
