Cydia opens unauthorized iPhone app store

iPhone users in the know are well aware that there's a slew of apps that aren't available through the official app store. Late last year, "the jailbreaking community lives on and offers some very useful applications that you likely will never see from the App Store."

These include apps like , which lets you use your iPhone as a camcorder or , which allows users to use the iPhone's cellular data connection on their computer via a Wi-Fi connection.

All of these apps have been available through , a software installer developed by 27-year-old California graduate student Jay Freeman. Starting Friday, Cydia will be opening its own app store, providing a way for those jailbreak developers to easily sell their applications.

In , Freeman says that Cydia "intends to charge developers no more than the commission Apple does for his site's billing services." The Journal also reported that two more rival app stores are also underway, including one interested in "selling adult games for the iPhone."

In an interview for that article, Susan Crawford, a professor at the University of Michigan Law School, said that federal courts ruled that previous DMCA-related cases were less about preventing copyright infringement, but rather about stifling competition. "Courts have said you shouldn't use the DMCA to leverage your copyright monopoly into other markets," she said at the time.
