I wonder if the reason why they're bringing up Leopard is because there's going to be some sort of tie-in if you sync an iPhone with a Leopard-installed Mac, or because the iPhone OS is built on Mac OSX and until they upgrade some core technologies in OSX they can't make major changes for the iPhone OS, or because Apple's so busy with trying to get Leopard out, they don't have the resources to work on upgrading the iPhone OS more?
Hmmm ... questions from a geek with too much time on his hands. :D
