Motorola today announced a 4G phone for Sprint, the Motorola Photon 4G, while also promising to bring more than 10 new devices to Sprint and its prepaid brands this year.

The Motorola Photon 4G will support Sprint's high-speed, WiMax-based 4G network. It also will feature version 2.3 of the Android OS, a dual-core processor, and worldphone capabilities. It sports a 4.3-inch qHD display, an 8-megapixel camera, and the ability to be used as a wireless hotspot.

Motorola also announced the Motorola Triumph, which will run on Sprint's Virgin Mobile prepaid brand. Its features include a 4.1-inch touchscreen, front- and rear-facing cameras, and a slim design.

Rumors have suggested that the Motorola Droid 3 -- the follow-up to Motorola's original Droid and the Droid 2 -- would make its debut this month. And while we haven't gotten an official look at the new phone, it seems as though a few Web surfers were able to get a sneak peek at the new device, thanks to videos leaked on a German phone blog.

The videos, which have since been pulled off of YouTube, showed what looked to be the Droid 3 in action. According to CNET, the clips were "brief but official-looking video tutorials." CNET notes that videos didn't show anything groundbreaking, but showed the phone having an HDMI port and a 8-megapixel camera.

The videos are no longer playable; clicking on them brings up a message that says "This video is no longer available due to a copyright claim by Motorola Mobility."

T-Mobile is adding yet another smartphone to its lineup of 4G phones. The newest addition is the HTC Sensation 4G, which offers a high-speed 1.2-GHz dual-core processor, support for T-Mobile's 4G HSPA+ network, and an impressive collection of entertainment options.

The HTC Sensation 4G will be available on June 15 for $199.99 after a $50 mail-in rebate. That price requires a two-year commitment to one of T-Mobile's voice and data plans.
