Not long after the U.S. Library of Congress ruled that jailbreaking iPhones is legal that the first “jailbreak” for the iPhone 4 was posted.
A well-known hacker who identified himself as Comex is said to have contributed the “update” that is available at jailbreakme.com. The hack reportedly installs a program that lets iPhone 4 owners and others purchase apps from stores other than the Apple App Store.
After jailbreaking their iPhone 4, users can already download apps that Apple has not approved for sale in its online App Store.
Jailbroken iPhones can then be unlocked and configured to work on wireless networks other than AT&T, which is the only official U.S. carrier for the iPhone. Unofrtunately, due to technical differences, jailbroken and unlocked iPhones will still not work with Verizon or Sprint.
A caveat though, other users who have tried the hack complained that it unintentionally disables the iPhone 4’s video chat capability and creates problems with multimedia text messages.
Comex said on his Twitter feed on Monday that he is trying to work through those issues.
