You may not believe it, but it's just been one year since the Apple App Store was launched! The App Store is a platform for the iPhone and the iPod Touch where users can download applications to enhance the experience from their mobile devices. Just recently in April, the App store saw its 1 billionth download (OCC News), a number that has increased to 1.5 billion up to now, which is only 3 months behind the 1 billion mark. Recently, downloads have been fueled by the release of the iPhone 3GS. Apple says there are about 65,000 apps available for download, a number that is steadily increasing. However, some of the developers are not happy with Apple's ambiguous policies regarding which apps are approved and which are not. For example, an application that lets the user watch live baseball matches was approved, however an app that allowed for TV on the go was not. Even at the WWDC, Apple did not answer any questions regarding these policies, but only told the developers to go to the website for clarification.Of course, a working concept is often copied, as is the App Store. Phone developers Palm, RIM and Nokia have launched similar platforms for users to download applications to their mobile devices. Google Android and Windows Mobile also have the option of enhancing the operating system with programs. Verizon might also launch an App Store for their devices soon.
