I am thinking about upgrading but have some questions: 1. What is the easiest way to upgrade and retain all my apps/repos in cydia? 2. Do I upgrade by doing a clean install or the upgrade option? 3. If I do a clean upgrade/install can I restore my old settings, etc? 4. Is it worth upgrading? e.g. are the improvements worth it, is there a new version coming out soon I had a hassle with the 3.0 upgrade so this is why I left it till now. thank you.
