im not sure who makes this phone but i have one similar to it (tmobile mda) and im sure it should be windows mobile? it's pretty hard to adjust to if youre using a normal phone (not a pda or smartphone). just dont give up so quickly, it took me a few weeks to get used to and i consider myself pretty good with electronics & technology. it's a pretty good phone after you set sail: good camera, battery life, music player, and it has word & excel. a down side is that you cant get downloads from your mobile provider (ringtones, games), however you can upload music onto your phone and set that as your ringtone which is better anyway. also, the usb that connects the phone to the computer can also be used as a charger. it may lag sometimes, even though its one of the fastest smartphones. oh and its touchscreen which i prefer over the sidekick and blackberry.
