I have had 5 random reboots since yesterday and one semi bootloop.
Liberty Justice
That totally sucks. Fix permissions and all that funky jazz? Fixing the permissions seemed to work leonozug, it fixed the force closes for me and thats about it. I've gotten two reboots since yesterday, many force closes before fixing the permissions, but the phone hangs on almost everything. Loading the market is a nice 45 second journey for me on WiFi, usually it's instant. The time from me clicking send to it showing up in the list in SMS is a nice 30-second staring contest as well. Hopefully you get the point, as I could go on for a good 80% of my applications.
Again, all this will get fixed, it was in LGB. If no-one spoke up about it though, they wouldn't have a clue to fix it.
