David Pogue's Hot iPhone Tips

David Pogue returns with a thoroughly updated edition of iPhone: The Missing Manual. And now David shares some of his favorite, up-to-the-nanosecond iPhone tricks.

"The beauty of the new iPhone 3G is that you don't need one," explains David. "Almost all of the juicy stuff actually comes with the iPhone 2.0 software and the online App Store, both of which run perfectly well on the old iPhone as well."

Continues David: "That, incidentally, is also the beauty of "iPhone: The Missing Manual, 2nd Edition." It covers both the old and the new iPhones, because it covers the 2.0 software, the iPhone App Store, and so on."

And here are some of his favorites:

-- At the top of the screen, little icons indicate how you're connected to the Internet: an E for the vast but dog-slow AT&T Edge network, a 3G icon if you're on the faster but limited-area AT&T third-generation network, and radiating signal bars if you're on Wi-Fi.

The tip here: The two cellular icons (E and 3G) disappear whenever you're on Wi-Fi. That's not a mistake. The iPhone assumes that Wi-Fi is faster and better than any cellular network, and if you're on it, you don't care about E or 3G (and it's right).

-- Unfortunately, 3G is a battery hog. If you don't see a 3G icon on your iPhone 3G's status bar, then you're not in a 3G hot spot, and you're not getting any benefit from the phone's 3G radio. By turning it off, you'll double the length of your iPhone 3G's battery power, from 5 hours of talk time to 10.

To do so, from the Home screen, tap Settings->General->Network-> Enable 3G Off. Yes, this is sort of a hassle, but if you're anticipating a long day and you can't risk the battery dying halfway through, it might be worth doing. After all, most 3G phones don't even let you turn off their 3G circuitry.

-- More ways to save power: turn off more features. In Settings, you can turn off Bluetooth; Wi-Fi; GPS; "push" data; and the cellphone radio. Each saves you another bit of power.
