The specs for the Huawei U8680 were certainly not in the high-end category with a 4 inch WVGA display with a pixel density of 233 ppi. Under the hood is a single-core 1.4GHz Qualcomm Snapdragon MSM8255T processor with 1GB of RAM aboard. 4GB of native storage comes with the device although that can be raised to 36GB using the microSD slot. On the back of the unit is a 5MP camera with AF and an LED flash. A VGA front-facing camera tales self-portraits and enables video chat. The phone supports the 850/1700/1900 UMTS bands and Android 4.0 is installed.
Huawei requested a 180 days from the FCC embargo on the release of information about the handset, starting on March 27th. This points to a launch later this year. The current T-Mobile myTouch phones, the T-Mobile myTouch and the T-Mobile myTouchQ, are both made by LG and were launched on November 2nd. Similar to the Huawei units, one of the LG phones has a side sliding QWERTY while the other has just a virtual QWERTY.
