Seems there are a huge number of people who want to hack into their iPhone, as demand took down their servers for a period of time.
The software will jailbreak and unlock any first generation iPhone or iPod Touch running either version 1 or version 2.0 firmware, and will jailbreak the iPhone 3G. They’re still working on a way to unlock the newest iPhone so that it can be used on any other network.
Performing the hack isn’t for the faint-hearted, but then if you’re looking to load other applications onto the iPhone, you’ll soon be fairly intimate with the command line anyway. Currently, the software only runs on a Mac, but a Windows version is in the pipeline;.
Expect the cat and mouse game between Apple and the hackers to continue.
