If I buy an iPhone 4 and start a two year contract and cancel with at&t the next day can i keep my device? (there will be no termination fee within the first 30 days I know this for sure)

No. If you cancel within the first 30 days, you must return the Phone. Do you really think AT&T is that stupid?

iPhone 4 – Will you get it?
