Hi,
I first noticed this when i was i watching a youtube video.
and first i though that it was a the battery. But i keep on happenig more and more ofter. no idea what is triggering it. Once i was talking for a long time ( 30 min) on UMA(wifi) and it blacked out. Another time i was taking a picture, but the interesting think that is that the like stayed on while the blackberry was blacked out.

I can bring it back with a battery pull out, but sometimes it will just go to back blacking out after a battery pull and sometimes not.

If anybody has any idea please let me know.
