iPhone hackers have released a tool that allows owners of firmware 1.1.1 iPhones and iPod Touches to open up their devices to third-party apps - all without the need for a host Mac or PC.
The utility's called AppSnapp, and it's launched via the devices' Safari web browser. The code uses a known vulnerability with firmware 1.1.1, which it subsequently patches. Before doing so, it activates iPhones, jalbreaks both types of device to allow third-party apps to run, installs Installer, and allows the YouTube app to connect on non-AT&T iPhones.
Early reports suggest that AppSnapp does exactly what it claims, though the process may take a little time due to the number of users grabbing the code off the AppSnapp web site, jailbreakme.com
