This is what happened: First, when I jailbreaked my device (ipad 2 ios 6.0.1) using evasion, when I install a repo, it says "run apt-get update........". After hours of searching I knew how to solve it, but it didn't work. Then I ran the code "apt-get remove cydia" and "apt-get install cydia) to reinstall cydia. But after rebooting my device, when I click on the cydia icon, IT CRASHES! Do I need to make a full restore and jailbreak it again?
