If I don't unlock the phone shortly after it boots, it goes black and I cannot get the screen on unless I pull the battery. The backlit keys still light up but the screen is off.
I'm sure this has been covered but it is annoying.
EDIT: Just strange behavior out of mine. In fact, I have been having problems for the last few days with a lot of stuff. Market won't download (921 error) even after "killall drmserver" command, Titanium extremely slow restoring, extreme lag, etc. I feel like it may be my recovery somehow (4ext). I just haven't nailed down the problem. Just ignore this as I vent on paper ;)
