For those who recently jailbroke their iPhones are having issues with Cydia crashing when launching it. There is a quick and dirty fix for that and it requires to either SSH into your iPhone or use iPhoneBrowser and delete a few files. Checkout here on how to SSH your iPhone.

Apparently the problem is caused by some corrupted repositories that make Cydia crash within the first few seconds of loading it.

To fix this, simply navigate to /var/lib/apt/lists and delete all the files in this folder except for the folder called “partial”. Then reboot your iPhone and launch Cydia. It should load without crashing.
