T-Mobile said the Samsung Gravity would show up on Nov. 17th and, sure enough, it has arrived.

While the Gravity might not have the same pull as some of the bigger, less wallet-friendly QWERTY handsets on the market, at $49.99 (on a 2-year contract) it’s a decent pick for anyone looking to wear down their thumbs without wearing down their savings. It’s available beginning today in Aqua/White or Lime/Gray at the nearest T-Mo spot.

While the main draw would probably be the slide-out QWERTY keyboard, Samsung has also packed in a 1.3-megapixel shooter (with video capture and 4x zoom, though we’re guessing that’s not optical zoom), IM support for AOL/ICQ/Windows Live/Yahoo, T-Mobile myFaves, stereo bluetooth (A2DP), and quad-band radio. For 50 bucks, that’s actually pretty impressive.
