I have a unlocked Storm 2, I am currently on Iphone with the iphone data plan, I want to switch to bb BIS data plan. Can I just call in and have then remove the iphone data and add the BIS. Can I log into that AT&T Blackberry website after they change it even if I never had a BB on att to push the service books? Do I give them the Pin and IMEI from the storm 2? I have read tons of info but seems everyone was coming from another blackberry on AT&T
