1. Force-quit an application. Now
that the iPhone is a real handheld computer, it's not immune from the
occasional misbehaving application. If one freezes up on you,
force-quit by pressing and holding the Home button for 6 seconds.

Make reservations the easy way.

2. Make reservations the easy way. If
you're looking up a phone number for something in Safari—say a
restaurant or a hotel—there's no need to leave the page when you find
it. Simply tap the number right on the page; the iPhone will dial it
automatically.
3. Double-down with scrolling. Many
Web pages contain separate text boxes with their own scroll bars. If
you're trying to move around in one, try this: Zoom in, and then scroll
with two fingers instead of one. That will let you scroll just inside
the box and not affect the position of the entire page.
4. Maximize battery life, part 1. iPhone
and iPhone 3G models have more sensors than just the accelerometer. For
example, they have a separate sensor, situated right above the
earpiece, that detects ambient light. The iPhone uses this sensor only
once per session, though, just as you unlock the handset. But if you
cover the sensor as you unlock the phone, you will trick the handset
into thinking it's in a dark room, and it will power down the screen
brightness as a result.

5. Maximize battery life, part 2. The
iPhone's newfound e-mail synchronization abilities are useful, but they
also drain the battery more quickly. If that's a concern, under Fetch
New Data, set e-mail fetch time to Hourly, and turn Push off.
6. Grab a screenshot. The
latest iPhone software lets you easily take screenshots of just about
anything. To grab one, hold down the Home button and press the
Sleep/Wake button. The iPhone will deposit a photo of the current
screen in the iPhone's Photo application.

7. Get a bigger keyboard in Safari. Before
you begin browsing, rotate the phone horizontally. Now tap the address
bar. Voilà: a wider keyboard. Now if Apple would only add this feature
in more applications instead of just Safari….

Keep Safari's address bar handy.

8. Keep Safari's address bar handy. Ever
scroll pretty far down a Web page, only to find that the address bar
has disappeared? No need to scroll back up—instead, tap the top part of
the screen. The address bar will reappear, regardless of where you are
on the actual Web page.
