Blackberry - 8800 Smartphone Cell Phone Review

I purchased my Blackberry Pearl in October.  It is a great little phone and has many capabilities that I love (internet browsing, multiple email account setup, etc). 

 One thing that I have had major problems with on this phone is that the screen keeps going completely white for hours at a time and I am not able to see the screen, but the phone is still on.  It might just be a t-mobile problem, but it is ANNOYIING and inconvenient as it is my only phone and I don't own a landline. 

Bottom line is that I need a reliable phone.   So far, this has not been it.
