iPhone and iPod touch users have downloaded more than 100-million applications from its groundbreaking new App Store since its launch in July. More than 3 000 applications are currently available on the App Store.

Applications can take advantage of iPhone's large display, innovative Multi-Touch user interface, fast hardware-accelerated 3D graphics, built-in accelerometer and location-based technology to create mobile applications unlike any seen before.
"iPhone's unique capabilities, easy SDK and the ability to reach an audience of millions via the App Store made this an easy development choice for us," says John Pollard,CEO of  Jott. "To date, we've had hundreds of thousands of downloads of Jott for iPhone, which has been a major win for our company."
The App Store on iPhone works over cellular networks and WiFi, so users can wirelessly download applications directly onto their iPhone or iPod touch and start using them immediately.
Applications are free or charged to the user's iTunes account and the App Store notifies the user when updates are available for their apps.
The App Store is also available on iTunes for Mac or PC, which syncs applications to the iPhone or iPod touch using a USB cable.
