My phone is behaving more or less as described.
Just that it didnt start after OCing experiments (was 950 in Maemo and 1 Ghz in Nitroid - just to impress some applegeeks with the dualboot and standard nitroid is f slow. And it was stable that way for month. Sometimes getting warm, but nothing to special. I was more worried about the Battery.)
It started after the 1.3 upgrade i did on Friday.
Think ill have to try the Flashing. And give 1.3 a chance, because so far its not making me happy.
