iPhone/iPod touch development

Hi all,

I was just wondering how you go about developing games for the iPlatforms, I've got a couple of game ideas that would be perfect for these devices.

Any info you can give would be great; Do you need a mac or can you use windows? What SDK options are there?

If anyone has experience of iPlatform development and has any stories (good or bad) i'd be really interested in hearing them.

At the moment i'm not commited to anything and have other projects in the works but it's something I may want to explore in the near future

Thanks, Adam
