Figured out the issue with ESPN radio via a wider web search... apparently Froyo renders certain types of AAC music and streams differently than 2.1 does, so many are having issues with ESPN app unless they perform a convoluted ADB push edit, which apparently affects other aspects of the phone...
Aside from that, does 2.0.01 have GPS fix built in, because my GPS worked fine on all 2.1 ROMs and Quantum, but CANNOT find a signal on Epic as of yet... tried in 2 wide open areas this morning after giving GPS 5 minutes to find a lock where normally it would take 30 seconds or less... and I have an original Epic that was one of those phones that NEVER had GPS issues whatsoever... I'm perplexed because others report GPS working fine... this ROM can't place me closer than 2 blocks to my location in NYC in a wide open area...
