so here's the situation. I own a samung D600 and a Xcute DV2 and an MPX 220 (I am looking to sell a few of these phones) but anyway I am with tmobile and just added my wife to my plan. I have been out of contract for about 3 years now and my wife just slipped out of contract (she has an e635 that she wants to sell) anyway tmobile is offering us a tmobile SDA (for me)for 129.99 plus a 50$ mail in rebate and a T809 (for her) for 99.99 with a 50$ mail in rebate. Should we do it or shop around a bit more????
