I am just wondering. Instead of buying a phone off of the t-mobile site or in store can you find it on a different site and buy it, and then use it with T-mobile? Or do you have to buy it directly from them to use it?
For example could i buy the samsung expresso (a t-mobile phone) from another site and use it with them?
