Will an unlocked iphone work with sim card from a blackberry. I have a bb with an unlimited data plan and am curious if i can just switch the sim card out. Or do I HAVE to get an iphone data plan. I am currently an att customer, but can't get rid of my bb due to work, and was thinking i could just swap out the sim card on the weekends for iphone use and just the iphone as an ipod during the week.
thanks
