Hi everyone im sorry if this questioned has been asked. But if my brother has an AT&T account and has had a basic phone for 2 years and is eligable for an upgrade, could he buy the 3gs for $200 with the $30 data package every month, and give the 3gs to me (im on tmobile) and put his sim card into an IPhone 3g, which is my current phone, i am willing to pay him for both phones because he is helping me out. My question is, could this be a problem with AT&T, because he will be paying the $30 for 3G internet and will have have an iPhone 3g. So we are not trying to scam AT&T or anything because we are paying for the phone and the internet. Thanks.
