Verizon and Motorola are launching another DROID smartphone, the Motorola DROID 4, which is the thinnest and most powerful 4G LTE QWERTY smartphone. Like its predecessors (DROID, DROID 2, DROID 3), Motorola’s new Android device packs a QWERTY keyboard in a slim body. The DROID 4 adds support for Verizon’s 4G LTE mobile network for high-speed data.

T-Mobile announced the LG DoublePlay, an Android smartphone with a special design featuring a split QWERTY keyboard and two capacitive touchscreens. The new phone comes with a 3.5-inch main display and a 2-inch seconday display that sits in between the QWERTY keyboard. It runs Android 2.3 Gingerbread OS.

AT&T will release later this year the Samsung DoubleTime, a smartphone with a full flip keyboard and dual touchscreens. The phone has a 3.2-inch 320×480 touchscreen outside and when you flip open it, you can find another 3.2-inch touchscreen and a four-row QWERTY keyboard for quick messaging. It has a 3.2 Megapixel camera with video recording.

Other than the Torch 9850 and 9860, RIM has another new Torch, the BlackBerry 9810 with a slider form factor. As the follow-up to the 9800, the new model looks just the same but packs upgraded hardware. The 9810 runs the next gen BlackBerry 7 OS on a 1.2GHZ processor and 768MB of RAM. Other than the slide-out QWERTY keyboard, the phone also offers on-screen keyboard. It has a 3.2-inch 640×480 touchscreen, and a trackpad below the screen.

AT&T is launching Pantech’s first Android smartphone in the US market, the Crossover, on 5 June. This entry-level Android phone features a slide-out keyboard for easy messaging. It has a 3.1-inch touchscreen display, a 3 Megapixel camera with camcorder, GPS support and a microSD card slot.

AT&T is going to release on 15 May the HP Veer 4G smartphone. At the size of a credit card and no thicker than a deck of cards, the  HP Veer is the smallest full-featured webOS smartphone. The Veer 4G, as its name indicated, supports tri-band UMTS 3G, HSDPA Cat 10/HSUPA Cat 6 4G as well as quad-band GSM/EDGE networks.

Other than the new Pre 3, HP also introduces the Veer, the smallest webOS smartphone to date. With a slide-out keyboard, the compact phone is about the size of a credit card and no thicker than a deck of cards. It measures just 54.5 mm x 84.0 mm x 15.1 mm and is only 103 grams. One special thing about the Veer is that it doesn’t have dedicated micro USB port and 3.5mm jack, instead it has a 5-pin magnetic connector for attaching charging adapter and 3.5mm jack adapter.

HP has announced the new Pre 3 smartphone running webOS, which is a multitasking professional workhorse that’s perfectly balanced for speed and serious fun. Like the Pre, Pre Plus and the Pre 2, the Pre 3 with the HP branding comes with a sliding QWERTY keyboard and it also gets a large 3.58-inch 480×800 WVGA touchscreen. It sports a 5 Megapixel auto focus camera with LED flash flash and 720p HD video recording and a front VGA camera for video call.
