AT&T is all set with the HTC One online pre-orders beginning on April 4 ahead of the smart phone's availability on the network carrier on April 19. Consumers can choose between the HTC One 32GB version at the price of $200 and the 64GB version that costs $300.

According to the Engadget.com report, the would-be owners of the HTC One smart phone can purchase the 32GB version at a price of $249.99 as part of the new two-year contract. The HTC One 64GB version is worth $299 with the new contract but the release date has not yet been confirmed.

Furthermore, AT&T will offer the free Media Link HD to the deals as part of the HTC One pre-sale but the customers will have to wait until April 19 for its availability. AT&T plans to maintain the standard features on the HTC One smart phone but the carrier will reportedly add up their own branded features such as the "Ready2Go" service and "DriveMode" to avoid texting and driving.

HTC claims that their latest smart phone focuses on the camera performance as well as the hardware and software design. The "UltraPixel" camera image sensor can provide the captured images with larger pixels and a better quality under low-light surroundings.

HTC One features the 5.7-inch 1080p Super LCD 3 display with 468ppi in an aluminum frame powered with a 1.7GHz quad-core Snapdragon 600 processor, 2GB of RAM and LTE support.

HTC representatives announced during the smart phone's launch that it will be available from 185 carriers in 80 nations worldwide. Last week, the HTC One smart phone arrived in the United Kingdom but the United States release date has been pushed back by the end of April 2013 according to the HTC announcement.

No announcements were made regarding the HTC One release date in other carriers such as T-Mobile, Sprint and Verizon.
