tom3q, please tell me if I can do anything more for the Wi-Fi issue. Is there any quick way to fix it or should I go back to FroYo until you further investigate the problem? I don't mind at all testing and flashing like crazy . Shall I provide you any more details/logcats/dmesgs from this build or can I restore my backup? Thanks.
P.S.: Also, it seems like I don't have any Wi-Fi MAC address in Settings -> About phone -> Status
