Howdy!
Congrats on your good deal! I paid the full 200, oh well, I did pick up a car DC to USB converter and just plug my cable into that ($15).
A side note, these HD2's come with the "gorilla screens". The T-mobile rep took his keys and rubbed them back and forth on the screen, not one scratch. There is also some youtube video's showing people doing the same on their HD2's with razor blades and stuff. Good grief! they sure are making these screens harder then the old plastic covered ones! Well enjoy your phone!
