New 3G/4G not working with 2.9.21 for Galaxy S III -AT&T i747

Sep 25, 2012
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.
