I can say this much: if AT&T blocks my GoPhone use in my iPhone, I'll simply let my GoPhone account expire. The very reason I have it is to use with my iPhone in the US, and I'm not in the US anywhere close to frequently enough to justify having a postpaid account (that would cost me many times what I pay now anyway). If I had to, I could easily live with T-Mobile.
