Hmm, tried again, still boot-loops on my Droid... Great concept, I wish it would work. Also tried nightlies and CM nightlies and 7.1 Stable. Same problems. The latest GB version I've been able to run stably is 2.3.3 (CM 7.0.3). Everything else either crashes regularly or has hardware features (ie, camera, wireless, tethering, bluetooth, GPS) that don't work properly. I've got my two Droid1s pretty heavily loaded and customed out; it could be that a more vanilla droid would work properly with some of the newer versions of GB. I have scaled down a little, but I'm not willing to give up apps and features that I've paid for. GB 2.3.3 is pretty good, and with only a few minor exceptions, it's better for me than Froyo was. Still love my Droid1s, they still do some amazing things... But 2.3.3 is probably as far as they'll be going into future Android versions.
