Hi , im hoping someone can help me out .
I currently have an AT&T pick your plan , and have an opportunity to buy an Iphone , ive researched it and i understand that i can use the iPhone on a prepaid account , but all ive seen is people doing this by making a new acct .

I really like my phone number and would like to keep it , would it be possible to add unlimited data to my current plan and just put that sim in the iPhone ?

Or since it has to be activated thru itunes will i have to get a new prepaid acct and # ?

With my credit i will have to go prepaid , so a contract isnt an option for me .

Any advice , im supposed to check out this phone tommorrow and need to be sure i can make this work .
