locked up, forgot date & time - problems since Black update

[GregCh]

Anyone else had problems since the Lumia Black update? My phone locked up, completely unresponsive, I had to take the battery out and put it in again before it would work. Then today I noticed the date and time had reset to 7:00am on July 26th last year... I just wondered if anyone else had experienced these issues and what the fix might be?

Haven't got the black update yet but from my experience with my previous phones, taking out the battery resets date and time.

That would make sense, you're right. I was being an *****! Not sure why it locked up in the first place, though.
