Currently, I have a Blackberry Data Unlimited package on my account but I plan on getting the iPhone 4. Now it wont be my dedicated phone as i'll be switching in between the iPhone and the Blackberry for work reasons. The problem lies with the sim card. My blackberry has the regular sim and the iPhone 4 has that micro sim so I don't believe hot swapping is possible. Also another concern of mine is that when I activate the Sim card they will remove my Blackberry package and put the iPhone package on there. Is there anything that I can do to retain my blackberry package and have the iPhone 4?
