The iPhone hacking faithful can now unlock and jailbreak their original iPhone, iPhone 3G, and iPod Touch 1G devices with the much-awaited PwnageTool 3.1. Unfortunately, the hacking tool does not yet support the iPhone 3GS or the new iPod Touch, but an update is expected soon.
The new iPhone 3GS includes hardware-based encryption, giving the impression that your data is more secure than on previous models. A well-known iPhone security expert shows, however, that the data is just as easy to grab using simple hacking tools.
