I work for corporate at tmobile and can get you both with a HEFTY discount. let me know what you wanna do...
FYI the MDA is old and outdated...you may want to look into a dash (HTC--same company) or an unlocked 8525...it will be the MDA II, but tmobile wont carry it for another 3 months...
Anywho, get at me, I can hook you up on ANYTHING that has to do with tmobile
