So last night I updated my iPhone 3 to 4.3 and now it randomly restarts. It will show up with the apple logo all dim, then the screen and logo will brighten and then it goes to the "slide to unlock" screen like everythings normal. It will just randomly do this throughout the day. I reset it to factory settings and it still does the same thing. I have since backed it back up though. So does anyone know how to fix this? Or does anyone have the same problem. I hope Apple comes out with a new patch or update to fix this issue or others as it seems like a lot of people are having issues with the update. Its getting kind of annoying Thanks a lot.
