Help! Some of my settings are missing

I wanted to clear the cache in safari this morning, and I noticed that when I went into my settings app, the safari settings tab and some of the others are missing. I have a 3GS, jailbroken. Any help would be greatly appreciated!

 

Before I get screamed at, I just want to say that I did search the forums for this issue, and came up with nothing, but after I posted the question, I searched google for "iPhone some settings missing" and it took me to a thread on Macrumors.

That being said, the only advice in that thread was to restore as a new phone (not from backup). Anyone have any less painful solutions?
