iPhone 3.1.3: All my UIButtons and UITableRowViews are now gray

Not sure how this happened, but all of the UITableRowViews and roundrect-style UIButtons in my app—spanning a dozen or so views—are now all gray instead of white. Unfortunately, I have no idea how this happened. (In fact, I had no idea it was possible to do this.) Explicitly setting the button's or tableRowView's background color to whi...

Hello, Is it possible to get a youtube video to autoplay on Safari and/or UIWebView?

Could this be done by faking a tap on the youtube video? If...

What could cause this difference in behaviour from iphone OS3.0 to iOS4.0?
