I have this red (1) next to my settings app and can't figure out what it means.

I already have iOS 5.1.1. Could it be that this is because I denied a baseband update on my new iPhone 4S? How can I update now? It won't work as said at Apple's support website (going to Settings > General > About and then a message should be shown).

Really, this (1) is annoying. Restarting the iPhone won't work, neither does synchronising.

Does anyone have any idea how to get rid of this?
