Screen lights up periodically?

[Guest Archy]

Can anyone explain why my blackjack's screen will light up periodically while its not in use?

...I dont seem to be getting any messages, im's, calls...

It's slightly annoying

Mine does that also, and its not when its switching networks or anything... ?

you may not be receiving anything but it's looking for something. most im programs cause this.

This happens to me and it occurs whenever I get a exchange pushes mail to me or when my gmail account syncs (every 10 mins) and pulls down an e-mail. My LED blinks purple a couple times when this happens.

Im not sure how to prevent this happening, but thats when it happens.
