Can you take the sim card from an iphone 4 and put in a BB using an adapter and not have to change data plans with AT&T? I'm having withdrawals from BB messaging/good phone functionality and want it back but still be able to use my iphone 4 for wifi/music/apps. Let me know what you think.
I think the iPhone4 uses micro sim, but not positive on that. If they do you'll need a micro sim to Sim adapter. Even after that I doubt you'll have access to the BIS as AT&T would need to enable that to your account. You should really call up AT&T and see if they can make your account work with both devices. I'm sure they'll want some extra money out of you for both and iPhone and BIS services though if they will give it to you.
made more sense to get the iphone since itouch's are just as much. Granted..I like the iphone but coming from the blackberry world you lose a lot on on the messaging hand but do gain a lot on the other multimedia/app hand.
