Veriozon reps are full of it because I've asked several and they have all told me that my iPhone will only work internationally and although it's unlocked it won't work with AT&T or t- mobile . So I was next to a t-mobile store yesterday and asked the guy if he could insert a SIM card to see if it would pick up their network and it did. The reps all asked why I was leaving and I said because it is too expensive. Sounds like they are trained to say that in order to not lose customers.
