My phone becomes completely unresponsive after I do almost anything in Cydia. Whether it's adding a repo, installing an app or removing an app, the phone stops responding to any input. The home button doesn't do anything and I have to wait about 20 to 30 seconds before I can do anything. Sometimes Cydia is still functional but the home button will not work and other times everything becomes unresponsive. Any thoughts? Also sometimes respringing can take a minute to three minutes also.
