1. a) Should I suspend my AT&T account (still costs $10/mo + tax) while I'm back in Australia? Or just get a new one when I'm back in the USA?
b) Do other USA mobile carriers charge for voluntarily suspended accounts?
2. Will be 1st gen iPhone work in Australia? Do I need to "hack" unlock or will AT&T unlock it for me after 2 years? Hmm...
