@chukdez: Check out the forums at CyanogenMod.com I think that they're still working on support for most of the myriad Galaxy S models (which includes the Epic 4G). Personally I'm looking at the Sprint Samsung Galaxy S 2 (Samsung Within) for my next device when I'm due for an upgrade in October. I hope that Samsung doesn't have such horrible issues updating the OS on it as they have on the originals though.
Back on topic however, while I have no specific issues with this ROM currently (since the microphone on my Bluetooth stereo headset is broken so I only use it for music), I'm glad to see someone still working on this ROM since I'd still like to eventually see a fully operational version of CM7 on the Optimus S. Before I even purchased this device, an LG spokesperson stated that it would 'eventually' receive an official update to Gingerbread. I'm guessing that an official 2.3 ROM (with source code) would make fixing the various issues MUCH easier. Well all I can do for now is hope I guess ^_^
