I jailbroke my phone using jailbreakme.com. Come to find out you are unable to change the homescreen wallpaper. Between this forum and a website I found I was able to do a work around. But the website I found had told me to add a source which I did. Now when I go into Cydia it gives me an error saying something about along the lines of it is unable to fetch it. So assuming it is unable to fetch it I guess it's doing no good to have the source but when I go to manage and sources it is not listed. How can I get rid of this error?
