Motorola Droid Bionic, one of the most anticipated smartphones this year along with iPhone 5 and Samsung Galaxy S2, is launching on Thursday on Verizon’s fast 4G network.

While iPhone 5 is still stuck in rumors about its release date and Samsung Galaxy S2 has faced reluctance from Verizon, waiting for Sprint to launch Galaxy S2 Epic 4G Touch after Sept.16, Droid Bionic has grabbed quite a bit of limelight.

Verizon will begin selling the Android 2.3-based Motorola Droid Bionic at $299.99 with a two-year contract.

Droid Bionic, which is a potential challenger to the iPhone 5, will come with a ZumboCast app, which lets you access videos, music, pictures and documents stored on PC or Mac. The phone also supports Video Surf, NFL Mobile, support for Netflix, Shazam-like app for videos and Motoprint for wireless.

Bionic is powered by a dual-core 1GHz TI's OMAP 4 chipset processor. It comes with 8-megapixel 3264x2448 pixels offering 1080p HD video capture. Droid Bionic is the first Verizon LTE phone to shoot 1080p HD video.

The phone also includes the Web Top application to connect to laptop and use the phone interface on the laptop computer, helping consumers to make calls, send texts, or run GoogleDocs, browse through Firefox 4 browser along with access to more than 200,000 Android Marketplace apps.

Consumers may have to shell out $299.99. But if they purchase it, they may get a $100 mail-in rebate on subscribing the minimum data plan of 5GB for $50.
