Iphone App Development for Beginners

I'm currently downloading the iPhone SDK and am planning to dive into application development. I'll be honest and say my programming background pretty much only includes experience with Perl, PHP and MySQL.

Can anyone recommend some good starting points for iPhone app development (besides Apple's site)

I see there's an O'Reilly book out... any other suggestions are welcome.
