I rarely spend much time with feature phones, but last September I took a look at the Samsung Gravity 2 and had to admit that was one fine messaging phone that has some excellent capability at a low price. Since then my youngest daughter received a Gravity 2 for her birthday and my middle daughter continues to use her first gen Gravity. T-Mobile announced three new messaging focused Samsung feature phones today for immediate availability; the Gravity 3, :) and Gravity T. Yes, you see that correct the second phone listed is the :) or phone currently known as the Smiley. These three phones range in price from $19.99 up to $74.99, with mail-in rebate and two-year agreement. All three support Exchange email (WOW) and T-Mobile Social Buzz (a new integrated social networking application).Gravity 3 just continues to build on a very popular device with much of the same in terms of specs. It has a 2 megapixel camera, full slide-out QWERTY keyboard, microSD card slot, integrated GPS receiver, integrated music player, and more for $49.99 after $50 mail-in rebate. Samsung :) is available now for $19.99 (after $20 rebate) and has a vertical slider form factor with the keyboard located under the display. It has a 1.3 megapixel camera, 3G wireless radio, integrated GPS receiver, microSD card slot, and typical basic feature phone functionality. It looks to be a fairly decent low cost messaging device that will probably be a big hit with teens. Samsung Gravity T is similar in appearance to the Gravity 3 with the side slide-out QWERTY keyboard, but incorporates a touch screen with on-screen keyboard. It also has a 2 megapixel camera, integrated GPS receiver, 3G data radio, and stereo Bluetooth support. The Gravity T is available for $74.99 after $75 mail-in rebate.
