If you were looking for a new Q10 or Z10 on AT&T you are going to want to check this deal out. AT&T has been giving $100 for awhile if you trade in your old smartphone in a store. Now a few users noticed that AT&T is offering the same deal on their website with an extra tweak. They are not really requiring you to send in your old phone. This means that upgrade and new contracts can benefit from 50% off from what we have seen so far.
