No ideas from me. I just got my BB on Monday. I actually wanted to ask you about your avatar. I can't remember the name of the cartoon the guy is from...
If you're using BIS, I've seen people delete their email accounts from the configuration and then re-add them. Not sure on BES. Also, is it all email accounts? Just one email account?
I have a gmail account and am still having hours of delay. I too have re sent service books, deleted then added account from BIS, and did several battery pulls. Still no better. It was instant for the first two weeks but been having problems since Christmas. Calling Verizon tomorrow
