iOS 4 Development

So I’m finally getting around to learning some Objective-C and hopefully doing some iPhone/iPad/iPod Touch/Mac OS X development. I’m currently going through Stanford’s excellent iTunes U offerings, following the lectures and completing the assignments. I have a really cool idea for an iPad game if anyone has any Open GL experience… Hopefully I’ll learn fast and I can get going on it!

If anyone has any tips/suggestions for getting started and/or targeting all the new iOS 4 platforms (iPhone, iPod Touch, iPad) I’m all ears! Particular things of interest are vector graphics and if there’s any way to incorporate them directly without rasterizing for a resolution independent solution going forward. Any Adobe Illustrator tips would be much appreciated too! (I have quite a bit of Photoshop experience.. almost no Illustrator experience though!).
