Spotlight Search in iOS ?
 

Just wondering if its possible :)

Last time I checked on this, third-party apps couldn't make information available for searching by iOS' version of Spotlight. IIRC, Spotlight only searches info from the Apple-supplied apps on the device.

It's possible that's changed in the intervening time - I'm pretty sure I asked about this in the iOS 4 days. If an engineer hops on later and posts different info, that's why. :-)

No! Apple won't let it - yet ...
