If you're an iPhone user, you'll find the just-released iOS 4.2 a solid, mildly useful new system update. There's nothing earth-shaking here, and nothing as significant as the multitasking features and folders that iOS 4.2 adds to the iPad.

Still, features such as Find My iPhone and the ability to search for text on Web pages in Safari will be welcomed by every iPhone owner, even if those extras won't mean a major change in the way you use your phone.

Find My iPhone

AirPlay and AirPrint, which I discuss below, will get much of the publicity with this new release, but for the absent-minded and the security-minded (like me), one of the niftiest aspects of the upgrade for iPhone users will be the Find My iPhone feature, which is now available even for those who don't currently use MobileMe. (It will only work on iPhone 4, the fourth-generation iPod Touch and the iPad.)

As you would guess from its title, Find My iPhone helps you locate your device if you misplace it. But it does more than that -- it also lets you remotely lock your iPhone, wipe it, display a message or play a sound on it.

The service is available through MobileMe, but you can turn it on even if you're not a paying subscriber. Add a MobileMe account by tapping Mail, then tapping MobileMe. Enter the Apple ID and password you use with the iTunes store. That will set up a MobileMe account for you.
