I jailbroke my iPhone 4s running iOS 5.1.1 this summer. I don't have very many things installed--no more than the average user, possibly a little less. I do have winterboard but I only run a couple of tweaks. For the last couple of months I've had the following problems: 1. My phone crashes/reboots often (daily) with increasing frequency. 2. When I've tried to update paid Cydia apps that I purchased through paypal months ago, for ex. Barrel, Color Keyboard etc., that show up on my list of changes/updates in Cydia I get an error message about how the action couldn't be completed because the package needs to be purchased first this isn't that big of a deal, I don't even mind repurchasing them, I just thought I included it if it might help someone identify the larger issue). Then, as of Monday when I try to open Cydia I get the following error messages: Wow, you exceeded the number of package names this APT is capable of. Problem with MergeList /var/lib/apt/lists/cydia.winterboarder.com__Packages The package lists or status file could not be parsed or opened And then when I hit the "return to Cydia" button underneath, I have the "Welcome to Cydia" home screen etc., but under changes the screen is completely blank, there is nothing listed. And when I search for something, nothing comes up. Over the last month, before the problem with Cydia loading, when I was just experiencing the crashing, I'd started going through and uninstalling apps/tweaks one by one (starting with the most recent and going from there) to try to weed out the problem, I was probably about 3/4s of the way through and nothing had changed in terms of crashing...and now I can't load cydia properly in order to be able to continue uninstalling things (though most of what was left, I'd had since I first jailbroke this summer and had had no problems with). My next step was going to be uninstalling Winterboard, but I'm not sure how to do that without being able to load my installed apps on Cydia. But now I'm wondering if I need to reinstall Cydia altogether? If so could someone explain how to go about that without having to re-JB? Or is there something else that I'm overlooking that could be causing the problems or that I could try to address them? Any help would be MUCH appreciated!! Thank you!
