Shold i wait and buy a N-Gage QD or take a 3650 ?
they have the same price (maybe the 3650 a little more expensive)
n-gage Qd or 3650
If the choice is between these two: Up to you. They have, basically, the same version of Symbian and Series 60 and thuse the same built-in apps, more or less.
If you want a built-in camera, infrared, and like an unconventional keypad and/or you want it now, take the 3650.
If you want a hot-swap MMC slot, a phone with more memory for apps & play N-Gage games and can wait for it to become available, take the N-Gage QD.
