The iPhone 2.0 update in June will have some improved features. With opening up 3rd party development, you can bet there will be some awesome applications that will be developed for iPhone. One of the new features is the App Store where one can go and download new apps for the phone. The AT&T 3G network will provide fast speeds too and that is coming very soon. I didn't buy an iPhone because of the lack of certain features but that may not be the case in the near future. Here's some links to check out:
