I will be leaving on a 6-week scientific field campaign to Arica (Chile) in mid-October and would like to take my iPhone (2G): email, Apps and (ideally) phone usage. However, if I did this I'd want to be sure that upon my arrival back to the States that I didn't have a whopping bill from AT&T sitting in my mailbox. One potential option that I've seen in our forum is that one can use Skype with their iPhone and that may probably be good enough. (btw, has anybody tried this yet?) Anyway, before I make any decisions, I'd thought I'd poll the collective wisdom here to see if there are other options.
