Coming six or so days earlier than anticipated Research In Motion today introduced the BlackBerry Curve, the smallest and lightest QWERTY BlackBerry yet. Known as the 8300 series, the updated phone features a large LCD screen, 2.0 megapixel camera with flash, an updated media player, microSD expansion capability (to 4GB), improved call quality, and more — all in a small package that is equally brilliant as it is beautiful.

According to the press release, the phone should launch on AT&T sometime this spring. (Which, might I add, totally blows.) Insider scoops have revealed the existence of two models: one featuring Wi-Fi, the other lacking. The initial model destined for AT&T looks like there’s no 802.11 goodness under the hood. The second model (dubbed 8320) does feature Wi-Fi, and is apparently headed for T-Mobile at some point, at least according to some covert folks in Waterloo (and, I should add, the fact that the T-Mobile Zen theme was preloaded solely on said device.)

There’s no word on pricing nor any definitive availability information at this point. Hopefully more information will become available once RIM kicks off the Wireless Enterprise Symposium in Orlando, Florida next Tuesday.

Of course, it goes without saying: I want one. Now.
