I've been running 3.0 beta for over a week with little to no problems since setting it up as a "new device". Yesterday, however, I had a strange experience. I used YouTube app ( it worked fine), but later that night a couple of apps began to crash. After a hard reset it simply didn't come out of it. The hard reset was followed by the apple logo which lasted forever. I repeated the process, same thing. Went to bed with the unit still showing logo and in the morning it was dead, as expected. Plugging it in, it finally reset itself and was able to load up and get to the home/apps screen. The only catch is now ALL of the native apps work fine but NONE of the installed apps wok at all. The "open" and immediately close. Has anyone experience this or have any ideas?
