While we're on the topic, here are a few of our own favorites
- The homescreen shortcut in firmware 2.2. With a click of the home button, you can jump to your first home screen.
- How to enable passcode protection. It's bad enough that you left your iPhone at the post office. At least the shmoe who finds it won't be able to call China.
- Pause an application download. Because sometimes you just don't have a free 90 seconds.
- Go Geocaching with an iPhone 3G. Who needs an additional GPS device?
