I was wondering if i can switch from blackberry to iphone?

Its been about 13 months, i'm under a 3 year contract with Bell currently using Blackberry 9810, and have a Blackberry social plan, along with 1gb of data, I was wondering if i got an iphone, i know the social plan won't work, but would the 1gb of data work on the iphone?

Also do you know if i can change my plan to iphone plan instead and get an iphone as well?

You can't since you still haven't exceeded the contract time
contact your carrier and tell them they should help you
but i persnally don't advise you to switch to the iphone
get a bold 9900 or something but not an iphone
i've got an iphone and i really hate it
