My Blackberry freezes itermittently...time and date shows incorrectly....will turn off by itself. Have you guys have similar problem? and what did you do to fix it?

I am thinking about resetting the unit to see if it will fix it. or removing the battery and putting it back inn. Please advice.

What model? 7100t? Seem to be a long standing issue with that unit... More details.

Thanks for the reply Finch, The model is 7280
