use a third party software to take pic of your screen. I can't make it out.

Any idea how I do that mate?

its the blackberry appworld update notification, load appworld n choose my world on right side youll have some updates to install

I use Snap Screen. Works great for me.

correct.
once updated, battery pull.
if notification still doesnt go away.
check in your MESSAGES folder and delete the message about it.

i think it's an msn update, only problem is i had to download msn from my computer onto my blackberry because i tried downloading on my actual phone but it constantly said 'starting download' and has said that for three weeks. only problem is it wont let me delete the actual download!
