So I talked to a t-mobile rep and asked him if I was able to get an upgrade, and the answer was no, not for 7 months Which is kinda odd because I got the G1 right when it came out and my wife got her myTouch when it came out and she is able to get an upgrade, but anyways, thats not the problem, here is the deal, since my wife is able to get an upgrade, I wanted to use her upgrade and get the nexus one, and simply...take her phone (the new nexus one) and use my sim card in it. The rep told me that the phone is tied to the phone number of the account whom you bought it through...so that means that even if I used my wifes upgrade, no other phone number/sim would work in it? That is my question...Anyone heard of this?
