The Apple iPhone already has access to more than 200,000 apps through the official store, but you can find even more functionality by considering some of the cool Cydia apps that are also available for download.
This policy changed over time, but for a while, the only way to get a third-party web browser on the iPhone was to use an "unauthorized" service like Cydia for jailbroken iPhones.
Among the cool Cydia apps that you can find through the repository, this is one of the best applications for the social media mavens in the audience.
So, what are some of the cool Cydia apps that you can download that are not otherwise available through the regular iPhone App Store?
On the flip side, you can then access a wide range of cool Cydia apps that are otherwise unavailable to regular iPhone users.
In short, Cydia is a repository of applications that can only be installed and run on jailbroken iPhones.
By jailbreaking your iPhone, you can then access a number of different apps through services like Cydia.
If you can't find it in the official App Store, consider searching through Cydia instead.
Listed below is just a small sample of what you can get from Cydia.
