I got word that T-Mobile has discontinued the original MyTouch model, now that it has been upgraded so don;t buy the older version that is still out there. Also heard there was going to be a re-release of the Fender edition.
T-Mobile is on backorder on the new MyTouch models with the more RAM and 3.5mm Jack until late March... They sold these fast and most retail T-Mobile stores I have visited don't have them either. Glad I got mine the day they came out.
