Am I allowed to run third-party applications on the iPhone?
The Apple App Store allows you to download applications (both free and paid) for your phone. The original iPhone didn’t support 3rd party apps, hence developers were forced to create web-based apps that they could run on the Safari browser of the iPhone. These apps did not run very smoothly, and they couldn’t use the advanced features of the iPhone, such as multi-touch. But, now numerous third-party applications are available that you can download and run on your iPhone. Check out the top iPhone apps to get some ideas.
