1. What mobile service do you have?

2. Have you had soft resets or white screens (leading to soft resets) the last few days?

3. Do you use SMS?

4. Do you use Goodlink?

5. Do you use Profile Manager?

6. What has seemed to be causing the problem, i.e., what keys have you just pressed or what messages have you just received?

My answers:

White screens (which cause me to soft reset)
Just about everything -- checking my email or Home Screen
