I've had the latest BB running for about a month now, but starting today it keeps freezing on me. I haven't installed any new apps in several weeks so I don't know what causing it. When I first boot the phone it runs fine, however I can tell it is continuously getting slower and slower by the minute. After being on for about 3 minutes it comes to a halt and the screen is frozen. Won't respond at all, won't turn the screen off, won't go to home, etc. etc. I noticed that every time it hits the completely frozen state, an icon pops up on my notification bar in the top right, looks like a little refresh symbol. It woudl seem it freezes trying to sync something?
