I started a thread ( http://forums.macrumors.com/showthread.php?t=1527170 ) a couple of weeks ago about a problem I was having with my JB iPhone 4s running 5.1.1 wherein every time I opened Cydia I would 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 would have the "Welcome to Cydia" home screen etc., but under changes the screen would be completely blank, with nothing listed. And when I'd search for something, nothing would come up. Under that thread someone had suggested that I do the following to reset Cydia: Navigate to /private/etc/apt/sources.list.d, Delete the file "cydia.list", Navigate to /var/lib/apt/lists, Delete all of the files in this folder except the one called "lock", Navigate to /var/lib/apt/lists/partial, Delete all of the files in this folder, Navigate to /var/lib/cydia, Delete the file "metadata.plist" This worked, but then when I started to re-add sources to Cydia, at about the 5/6th source, the same error message/problem occurred again. Accordingly, someone suggested I DL iCleaner from Cydia and turn on Cydia clean options. I did this, but did not end up trying to add sources back again because the news about the 6.1 JB came out and I decided I would just wait for that and restore/re-JB which I believed would SURELY eliminate the type of problem I was dealing with. However, yesterday I plugged into iTunes, did a full restore to 6.1, then restored from back-up (so I would have my settings/contacts etc.), and jailbroke my phone. Everything went COMPLETELY smoothly. Then last night I was trying to add sources to Cydia and on about the 6/7th source I got the SAME error message about "wow you exceeded...blah, blah, blah"... . I had not installed any packages or tweaks yet. Is this something that could have carried over because I restored from back-up after I did the fresh restore? Do I have to restore my phone and set it up as "new" to fix this issue? If so, there any other way besides restoring from back-up that I can restore my settings/app data/contacts/notes etc.? (I just have a lot of things that would take ages to re-enter manually--and particularly with application data, I don't even know how I could back that up another way?) Or is there some other fix for this that I can try? I know this is a long question, and there are a lot of ppl on the boards right now in need of assistance but I would be SO incredibly grateful for any advice anyone could offer on this. Thanks!
