no warning. Was running the leaked 595 GB and running perfectly for many weeks. Was playing words with friends, listening to music at the gym, watched a movie, no issues. Went to check email, phone is slow, locks up, screen will not turn off, had to pull the battery. Tried to clear the cache, no fix. Did a factory reset, same problem. Used RSDLite and SBF'd back to stock Froyo, still jacked up. Pulled the SD card in case it was corrupted, same problem. Gmail app keeps crashing, phone stops responding, can't get it to make a call, etc... Tried everything and the SBF didn't seem to fix it. Phone seems completely hosed, no warning, have not done anything with it to cause this from what I can see. Any ideas?
