Sometimes I see status updates on my Facebook Wall that I want to share, but only with a specific person or two, along with my private commentary. Is that easily done on Facebook?

I'm addicted to Facebook and am constantly posting updates from the Facebook app on my iPhone. Recently a friend pointed out that everything I post is only to friends, not to friends of friends or the public at large. For some of my updates, that's fine, but for others I do want it in the public eye. How do I change the Sharing settings on a wall update within the iPhone Facebook app?

I rowed with my girlfriend and posted something terrible on my status. Now we're friends again and I can't delete it...No option, remove or delete buttons...? HELP!

In a note over on your Ask Dave Taylor Facebook fan page, you said "you can mark your updates as only accessible by a subset of your Facebook friends". Dave, How is that possible?

I know that Facebook has fiddled with its privacy settings, but I'm wondering if I can now post status updates that aren't for the entire world to read, but just my friends? In fact, weren't old updates just for my friends anyway??
