The Huawei MediaPad seems to have quite some bits and pieces available as open source, including Kernel, Bluez and WebKit:
HUAWEI MediaPad - Huawei Device Co., Ltd..
The same goes for the P1 dual core phone:
Huawei Ascend P1 - Huawei Device Co., Ltd..
Is this any useful for porting or would we need other bits to be open sourced as well?
