Remove iOS 5.1 notification from the main screen? I do not want to update my iPhone 3gs to new iOS 5.1. How can I remove this notification showing all the time on the Settings images. Please look at the image. 



I've tried opening this screen but without clicking the button Download and Install, but the notification is still there. 

PS. I am new to iPhone. I have it for a couple of days.
I see that your iPhone is jailbroken. There's a tweak for this called noOTA badge. I haven't used it myself, but it looks legit. Give it a shot!
