Pop musicians have been endorsing products as long as they've existed (who could forget Beatles toothpaste, Ricky Nelson hand sanitizer, or Enrico "The Great Caruso" Caruso-brand horse polish?), but for some reason the convergence of the two never fails to amuse (and annoy) us. Even more so when sensible boy band yelper Jesse McCartney, um, flips out his Motorola Flipout Android phone to surreptitiously film some hard working dancer's backside. Is that how a celebrity should act? We think not! Video after the break (if you really want to, that is).

Looking to get an Android device on AT&T? Then you're soon going to have a few more options to consider -- the carrier has just announced three new Android-based phones from Motorola. Those include the touchscreen-only Bravo (not to be confused with the HTC Bravo), and the QWERTY-equipped Flipout and Flipside, all of which will ship with Android 2.1 and the latest version of MOTOBLUR. Of the three, the Bravo is the highest-end, with it packing a 3.7-inch 854 x 480 display, an 800MHz TI OMAP 3610 processor, a 3-megapixel camera, and DLNA support for media streaming. The Flipout and Flipside, on the other hand, each pack a 720MHz TI OMPA 3410 processor, the same 3-megapixel camera, and a 2.8-inch QVGA and 3.1-inch HVGA screen, respectively. Somewhat notably, the Flipside also boasts a surprisingly large trackpad, which AT&T says will let you navigate with one hand while keeping your fingers off the screen (though it does, in fact, have a touchscreen). Look for the Flipout to be available first on October 17th for $79.99 on a two-year contract, while the Flipside and Bravo should be each available before the holiday season for $99.99 and $129.99, respectively.

P.S. - We just heard from a trusted source that the Bravo and the previously-leaked Kobe are, in fact, one and the same. Nice to close that thread, then.
