In addition, T-Mobile has used Nuance's Dragon Dictation voice-recognition technology
in MyTouch 4G with their "Genius" button, which allows you to trigger calls or web searches, or dictate SMS or email messages. It's quicker than Google's system.
WiFi Calling
myTouch 4G features WiFi calling, using T-mobile's UMA support as freshly added to Android, and it is T-mobile's first attempt on the Google platform. Because of the no so good voice quality and the overall performance, some improvement is needed in its future software versions. Meanwhile, with myTouch 4G we can access to Skype, Google Voice or any of the other VoIP clients available in the Android Market.
Summary
The T-mobile MyTouch 4G features a thin and sturdy design. This Android 2.2 device supports the carrier's HSPA+ network and offers Wi-Fi calling and mobile hot spot capabilities. T-Mobile MyTouch 4G also has a 1GHz Snapdragon processor and a 5-megapixel camera. Although the video chat works not very well and its speakerphone volume is a little low, overall it is hard to argue with the T-Mobile myTouch 4G; this is definitely one of the best Android devices on the market today.
