after few tests.. myn's warmdonut is almost usable.. cm6rc2 is far from stable.. desktop seems to be responsive and menu loads fast but after sending sms i was trying to go back to desktop and it took forever.. i can make calls, send and recieve sms, 3g and wifi works like a champ. my problems - mp3 are played from speaker instead of headphones (wired headset) and i cant pair with my a2dp headset (which worked perfectlly on cm5 on my g1)
last but not least.. battery indicator is messed up. it shows 30% (winmo showed 70), after connecting charger it change immediately to "charged" and after reboot to winmo it shows 69%...
otherwise - GREAT WORK, i think when cyanogen release stable 2.2 it will be worth of work to port.
(sorry for my english..)
Headphones sometimes doesn't work and is a know bug,battery indicator is a known bug either
