OK. I was using POP service till this time.

Today decided to reconfigure my gmail account on blackberry.

Followed instructions on
BlackBerry Storm Wiki: Set up Gmail IMAP

But it did not worked. Keep getting message saying
"An error occurred during account validation..."

Here is a fix to it: follow this link and complete Captcha test, after that I was able to finish setting up my IMAP account on BIS.
