Alright so I plan to get a plan for my blackberry so i can use internet and other things to the fullest extent. however i also have a iphone 3G lying in its box all brand new. i have decided not to sell it and instead keep it. Now i heard that i need the blackberry plan to get email showing up on my blackberry. otherwise i'll get nothing. I was wondering if i buy the blackberry plan for for my current number. can i use it on my iphone and the data services will all work? i have heard of ATT switching your service to an iphone plan or perhaps using a iphone plan primarily, and email and data will still work on my blackberry? i did some research and both the iphone and blackberry plan will cost the same for me either way. so the cost isnt going to change right now. i just need to know if i should get a blackberry or iphone plan. and will email work on my blackberry if i buy a iphone plan.
