Since I've installed a few jailbreak tweaks, my iPhone has been crashing fairly regularly and I would like to know exactly what's causing it.

Does anyone know the direct path to where the crash logs/reports are stored on the device (/var/mobile/, for example)? This way I can clear all current logs, to start afresh, and I can extract them for viewing on a bigger screen, etc. Or does anyone know of a more advanced way to interact with and analyse the iPhone's Diagnostics & Usage data, in general?

The official logs and crash logs in on the path /var/mobile/Library/Logs. You can also download syslog. And get his logs from /var/syslog

Thank you, elibyy. :) – mythofechelon May 16 '12 at 8:01

Crash Reporter is a convenient tool for viewing recent crash reports on a jailbroken device - it's a free package hosted by BigBoss repository.

You can also view your syslog on the device by installing syslog > /var/log/syslog (a free package hosted by Cydia/Telesphoreo repository), rebooting your device, and then using your favorite tool to view it at the command line (see here for slightly more detailed instructions). The syslog records where each crash report is saved.

Is there nothing for the desktop? It would be preferable and more convenient if I could interact with the reports from the desktop. Bigger screen, windows, and all that.. Or do I use the syslogs to find where they are and then extract them to the desktop? – mythofechelon May 15 '12 at 11:31
I would suggest copying your syslog to your desktop and then also copying the crash reports too. OpenSSH on the device + a desktop SFTP client (like Transmit or Cyberduck) can make this easier. – britta May 15 '12 at 22:58
Yes, I know that. But, as I said in my question, I need to path to the reports and logs. – mythofechelon May 15 '12 at 23:27
