I was really looking forward to iPhone 4, but now after upgrading my 3GS to iOS 4.0 I'm not sure why I would upgrade. It's really that good. Which is great from a longevity point of view, but not from a gadget-lust point of view. I still have over a month to decide anyway, as they don't come out in Australia until late July. Unless they're delayed, like the iPad was. First world problems...
