You shouldn't be having those kind of issues with CM though.
If you want, I'll take the phone off you and fix it completely in 1-2 hours. Up to you.
But yeah, can't wait for the CM5 update.
Rukas, Droid won't run flash out of the box, but you can either sign up to for the Android Flash beta program using the link that masta provided, or you can wait until Android 2.2 gets released (which I reckon will be next month at Google I/O conference). My theory is that Flash will come integrated with the 2.2 update.
