Chicago (IL) - Yes, Apple's App Store carries great stuff for your iPhone. But some of the best applications Apple banned from the App Store are now found at an unauthorized store, called Cydia. Many have not yet heard of Cydia because it cannot be used unless you jailbreak your iPhone, a hacking process that preps the handset for running Apple-sanctioned programs. As of today, The Cydia Store gets into the game by enabling sales of sanctioned applications for the same 70:30 revenue sharing model that Apple offers. But Apple is already prepping to send its legal sharks after The Cydia Store by leveraging DCMA in order to push jailbreaking into illegal territory. The question is, does it make any sense at all? If you ask authors of ingenious programs that Apple banned from the App Store for questionable reasons, or for the users who obviously want to run them, Apple's response is a stifling action against competition, one that threatens to kill the best iPhone software out there. But if you ask Apple they'll say: a lawyer a day keeps the illegals away.

Jailbreaking was/is a commonly used hack, one that opens up the handset to install third-party applications -- originally at times when there was not yet an App Store or even the official software development kit (SDK) to allow the creation of third-party programs. [Editor's note: When iPhones are jailbroken, Cydia and Installer are both automatically installed as part of the jailbreak process, from there the Cydia App Store is accessed -- it does not have a generic homepage.].

Soon after jailbreaking allowed access to non-Apple software, central repositories like Installer and Cydia emerged to allow users to browse, download and install unofficial iPhone programs on jailbreak phones. This unfed desire of consumers convinced Apple to bring the official SDK and unveil the App Store in July of 2008, but it was through Cydia and Installer that we discovered and installed the first innovative iPhone programs -- bar Apple's own.

In many ways, Cydia has offered us a glimpse of the true potential of the iPhone platform with applications like iBeer and Popcorn which first appeared as unofficial releases.

Cydia Store challenges the App Store

It shouldn't come as a surprise that Jay Freeman, a 27-year-old California graduate student who created Cydia, is now upping the ante and challenging Apple by opening The Cydia Store for business. And why not? After all, Cydia hosts a number of interesting applications you're unlikely to see on Apple's App Store. Titles like Cycorder, the application that enables you to use iPhone's camera to record video. Or the $29 PdaNet tethering program which replicates the functionality AT&T promised they would deliver "soon" -- but is still nowhere to be seen.

As of today, programmers can even sell their applications on either Apple's App Store or Freeman's Cydia Store. Both stores offer similar sales terms. Freeman told the Wall Street Journal that Cydia will charge developers "no more than the commission Apple does for his site's billing services." According to the paper, two more unofficial stores are also coming, like Rock Your Phone and another that plans selling adult iPhone games. But why even bother anyway -- you might ask.

Did Apple's App Store kill jailbreaking?

It is true that the advent of Apple's App Store at first subdued consumer interest in jailbreaking. But as more and more great programs were rejected from their App Store, some are once again turning to Cydia (and similar sites) to get the software that would've otherwise never reached consumers because of Apple's App Store policies. For example, when Apple banned the podcasting program called Podcaster on the grounds that it replicates an iTunes feature, the developer who created it simply posted it on Cydia. Many other iPhone applications banned from the App Store for various reasons have also found their home on Cydia as well. The only problem is, using Cydia to install sanctioned applications requires jailbreaking the handset, and Apple plans to leverage this fact in order to kill the rival stores.

CYDIA HAS THE BEST SOFTWARE
Cydia offers programs that would have never been approved by Apple. Pictured above is the home screen of a jailbroken iPhone to accommodate two unauthorized stores: Cydia and Installer. Using these two stores and the jailbreak iPhone, you can browse and install all the software that Apple says is no-no on the iPhone -- like skinning application to personalize the UI, video recording, modem tethering, direct podcast downloading, and much more. But it does require you to jailbreak your iPhone first, which not only reduces stability of the handset -- but may become illegal if Apple gets its way.

SANCTIONED APPS NOW SELL ON CYDIA
As of today, programmers who saw their applications banned from App Store can sell them on Cydia. Jay Freeman (who created Cydia) says he's offering a comparable 70:30 deal like Apple does, whereby authors receive 70% of the sales price of every download, and Freeman keeps 30% to cover the billing system costs.
