Very useful iPhone tips

The blog Tap Tap Tap has posted a wonderful list to 10 iPhone tips and tricks you should know, including taking a screenshot (here's our how-to on that trick), enabling caps lock and customizing the home button's function. Definitely check it out.

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?
