Im with verizon and I have a blackberry. The reason why I haven't upgraded to the iPhone on a contract is because I have the unlimited data plan and if I sign a contract to get the iPhone i forfeit my grandfathered unlimited data plan. So to keep the data plan I need to buy the physical phone itself with no contract.

So now my question is, right now I have a blackberry so I guess I'm on the blackberry network or whatever (idk the technicalities with cellphones). If I deactivate my blackberry can I activate the iPhone I just bought or do I have to take it into the verizon store?

The thing is that I am in college and my parents are the one who are the account owners and right now they are in NY and dealing with the crisis of the store so they can't help me.

Thanks for the help!
