I've had the Galaxy S III for about two months now. (Upgrade) am I able to return it to T-Mobile and add money for the Galaxy note II? I have a little dent on the side of the phone.
There is a 30-day trial period when you upgrade your phone. After that 30-day trial period you are stuck with the phone you purchased. To get the Samsung Galaxy Note 2 you will have to pay a No Commitment charge on the phone which is about $700
