Also adds iOS 3.2.1 support
First made available over the weekend, the iPhone Dev Team's JailbreakMe site has already been updated to solve several problems. Hackers should now be able to properly use FaceTime on a jailbroken iPhone 4, along with MMS messaging. iPad owners should finally be able to jailbreak iOS 3.2.1, though some problems are said to exist with 3G iPads. Wi-Fi iPads have not had similar trouble so far.
JailbreakMe relies on an exploit in mobile Safari to enable installing unofficial apps. Particularly because the exploit involves a web vulnerability, Apple is likely to try and block JailbreakMe via the next firmware update. Jailbreaking is technically legal in the US, but it's strongly frowned upon by Apple, and voids the warranty of any iOS device.
