Rumored to be heading towards T-Mobile’s stores for quite some time now, the carrier's latest addition to the myTouch Android smartphone lineup has finally gone official, promising users the ability to reach 4G speeds on T-Mobile’s new HSPA+ mobile broadband network, as well as plenty of other cool features on the side.

Unlike the iPhone 4, that only works on WiFi networks, the Video Chat feature on the new myTouch enables customers to connect to other people through T-Mobile’s network or Wi-Fi.

With the myTouch’s front-facing camera paired with Video Chat through Yahoo! Messenger or QIK, customers can hold video conversations with friends and family who have a new T-Mobile myTouch, other compatible mobile device or PC.

Designed by HTC specifically to deliver 4G speeds on T-Mobile’s HSPA+ network, the new myTouch will offer customers fast access to websites, applications, videos, downloads and more.

Furthermore, the myTouch also sports a high-quality HD camcorder and, with a few touches of the screen, customers can share their photo albums, videos and movies wirelessly with a compatible HDTV or other DLNA device.

The new phone also includes three exclusive myTouch features: Genius Button, powered by Dragon Dictation from Nuance, which lets customers call, text, e-mail or access the internet with a simple voice command, Faves Gallery, which offers shortcuts to one’s most-contacted family and friends and myModes, which creates customized home screens for work and home.

The new myTouch features a 3.8-inch WVGA touch-screen display with virtual keyboard and Swype for easy text input, while also packing a second-generation Qualcomm Snapdragon 1GHz MSM8255 processor optimized for speed and graphic performance, a 5-megapixel camera, a preinstalled 8 GB microSD memory card, and an integrated media player that brings together favorite music, video and internet radio under one set of controls.

Powered by Android 2.2, the myTouch offers access to more than 80,000 applications on Android Market from games to location-based social networks to on-the-go shopping and more.

Unfortunately, we haven't been able to come up with any pricing details, but T-Mobile does inform us that the myTouch is expected to be available in time for the holidays in four colors — white, black, plum or red.
