AT&T has released one of the long-awaited 4G LTE smartphone HTC Vivid on its network. The latest mobile from HTC will be available from Nov. 6 in stores and online for $199 under 2-year contract.

Vivid packs a dual core 1.2 GHz processor and a 4.5-inch qHD display. The smartphone runs on Google's Android Gingerbread operating system (OS). It is one of the first smartphones able to utilize both LTE and HSPA+ 4G speeds, which allow owners of the smartphone reliable connection in both areas where applicable.

HTC Vivid will certainly face stiff competition from Apple’s iPhone 4S, which was unveiled on Oct. 4, instead of the eagerly-anticipated iPhone 5. The latest smartphone from Apple received an overwhelming positive response and sold 4 million units during the opening weekend.

iPhone 4S missed some prominent specs like edge-to-edge design, a larger display, 4G LTE and Near Field Communication (NFC) technology. However, it featured some important upgrades that were rumored to be a part of the imaginary iPhone 5, like the 1GHz dual-core ARM Cortex-A9 processor, PowerVR SGX543MP2 GPU, an Apple A5 chipset and an 8-megapixel camera. It also has a 3.5-inch TFT Retina multi-touch display and is loaded with the latest Apple operating system iOS 5.
