First and foremost, there's the 3G S. Apple's released the Technical Specs to give you a sense of what kind of hardware upgrades the new phones pack. Along with the long-awaited MMS capabilities, the upgraded camera that now captures video, and the increased selection of languages, the familiar touch screen's getting a makeover as well.

This small, new development is a fingerprint-resistant oleophobic coating, that keeps your screen smudge free. We suspect that also includes the inevitable ear-print smudging that accompanies any actual phone use. Of course, with the prevalence of protective screen overlays this seems the kind of feature we'd not really notice all that much.

Perhaps one of the coolest new features in OS 3 is Find My iPhone. Doing just what its name says, Find My iPhone helps you track down a lost or stolen phone. A number of apps claim to be able to pinpoint your phone's location when you can't find it, though they require the person who stole or found your iPhone to actually turn on the app in the first place. Others like Zhiing can be used to send your location to another Zhiing subscriber but can't be used to ping the missing phone to get a bead on it.

With Find My iPhone, you can access your me.com account from any computer to locate your phone's approximate location on a map, send a message to anyone who finds your phone, or wipe the phone's memory and restore factory settings. This last feature comes in handy if you have no chance of retrieving your iPhone and wish to keep your address book and pictures out of the hands of strangers. It also adds a level security that will make the iPhone a lot more attractive to business users.

The biggest drawback to Apple's Find My iPhone, though, is that it's only available through the MobileMe service, itself $99 per year. Of course, if you're the kind of person who regularly misplaces things that's a small price to pay when replacement iPhones aren't subsidized by AT&T.
