The Chronic Dev Team has released a new tool called CDevReporter. It is designed to help find vulnerabilities in the iPhone, iPod Touch or iPad in order to create an untethered jailbreak of the iOS5 firmware. The tool works by sending crash reports to a Chronic Dev Team server where they are analyzed by the team to pinpoint usable vulnerabilities. This is similar to how Apple uses the reports to find exploits to close.

Here's what they had to say:
...the program copies all the crash reports off your device (which, under normal circumstances, would be sent right back to Apple), and instead sends this data to a secure, private server hosted by your friendly Chronic Dev team. Next, our program proceeds to neuter your copy of iTunes, simply by changing your settings to prevent your computer from sending any further diagnostic information from your device to Apple.
