Scan for Wifi networks on iPhone SDK

I'm looking for the API to search for networks on the iPhone/iPad, and get data from them. A private API is also OK, the app's for cydia.

I know it is possible, because I saw some wardriving apps (in the store). I want that functionali开发者_开发知识库ty in my app too.

Could you please help me out?

Thanks,

Yvan
