Where did it go?! I'm trying to implement the YouTube/MobileSafari style Search box in an app I'm developing with the official iPhone SDK but can't find UISearchField or an alternative to use.

I am currently using a UITextField in its place but it's not the same. I've tried UITextFieldBorderStyleRounded, which according to Apple is "typically used for search buttons" but it shows up looking like a regular text field (like the URL box in Safari).

Is this something weird with Aspen simulator that will work on iPhone OS 2.0 or what?
