Every once in a while, maybe 2 or so times a week, my blackberry will hang with the rotating hourglass. When this happens, the arrows indicating data activity are flashing furiously and the unit is completely immune the keyboard inputs (like the end key). It just happened again and I called it while it was doing this, after about 10 rings it went to VM and then I got a missed calls dialog even though the phone never rang. It doesn't seem to matter what I'm doing when this happens, it just seems to happen when it feels like it. It usually lasts about 5 minutes or so then everything goes back to normal.
Anyone else seen this or have any idea what it is?
