I have had the dreaded "ring issue" since firmware 1.x (phone doesn't ring when sleeping). There was a fix for it which involved changing a file in the power preferences (using WinSCP and all that).

That worked... until 3.0. But now the phone simply doesn't get the call period! Sleep or no sleep, it doesn't ring and sends the call straight to voicemail. None of the old tricks work and I don't know what to do. If you find a fix, please let me know...

(In the mean time I guess I'll try going back to 2.x, hoping that it will go back to the OLD crappy version which is better than the new REALLY CRAPPY version. )
