An old colleague of mine seems to find it funny to call me every now and than... very annoying, since I don't like the guy, but he doesn't seem to understand!
Now I'd like to block his number, but I see no option for this in the menu.
Can someone help me?

Aside from the iBlacklist available via jailbreak (which there isn't one on the 4S/iOS 5.1 yet...) - the only solutions to unwanted calls is either any blocking available via your service provider... or - a low-tech method: get a silent ring tone, and assign it to the person(s) you want to block in your contacts... and the only thing you'll have to put up with is missed calls on your call log that you can delete when they annoy you.
