I love the ROM, but 2 big issues prevent me from using it daily. Under 2.9.7 ROM, 3G/4G would not work well unless phone rebooted. Under 2.9.21 only wifi seems to work. Mobile data does not seem to work at all. As well, (apparently a CM 10 issue), the bluetooth feature works sporadically. Phone Bluetooth feature will disconnect from external mic/speaker after about 10 minutes, then reconnect on its own after 5 minutes more.
