Hi, So my company (<25 employees) is switching from ATT to T-mobile starting July 1st. I really want iPhone 4, can I buy the phone renew my contract and cancel my contract a few days later? I don't mind paying the ETF (I can bill it to the company), but I don't want to be forced to return the phone as I will still be in the first month of new service. Thanks! PS: I understand that the phone is locked, but it will be unlocked in the near future & worse case i can sell it to someone on ebay.
