Steve Jobs has announced today their official support for third-party applications on the iPhone. Along with this comes support for push email, Activesync and Exchange support (think Blackberry).

Lifehacker.com has the low-down on what this all means:

If official third-party app support piques your interest most, Apple delivered with some exciting announcements. First, if you’ve already jailbroken you iPhone or iTouch and experienced what installing apps is like through the excellent Installer.app, Apple’s official application management software, called the App Store, works just like Installer.app; it allows you to install, manage, update, or uninstall any application directly from your device, either over EDGE or Wi-Fi. Unlike Installer.app, the official App Store integrates with iTunes so you can also sideload apps through iTunes if you don’t feel like installing on-the-go.

Although we could all see this coming, one of the big concerns was whether Apple would start charging for the 3rd party iPhone apps. It turns out that they are leaving that up to the developers, they can choose whether or not to charge for the apps they make.

The App Store won’t be available till about June, which is when the iPhone 2.0 update is expected as well.
