Issue: I have 2. First, Uncaught exception: java.lang.nullpointer Details: Every time I reboot my machine (which is often do to second problem), I get this error message. The solution involving removal of my contacts and re-syncing is a problem since my current software isn't allowing me to sync the address book in the first place. (I have no idea why.)(See below for software type and version)

Second. Screen locks up at various times. (With nothing consistent in cause)Details: I have not been able to find any rhyme of reason for this problem. The only thing that seems consistent about it is that placing my phone in my back pocket, even for a few seconds, will cause it to lock up. That being said, it will lock up at any time, during any program usage, or none at all. I have had the alarm go off in the morning only to find that the only way to stop the alarm is to pull the battery. I have removed virtually every app from the device. The problem, so far as I can tell, was not timed in relationship to any software install to begin with, but I was hopeful. Let it also be said that I am pulling the battery to reboot my phone a minimum of 3 to 5 times daily. Last week it went for almost 2 days without a problem and then it started right back up. Sometimes I will have to battery pull to make a phone call and do it again to stop the phone call. It is that unpredictable.

BTW: Computer is using - Blackberry Desktop Software Version 7.0.0.43
