I have an itouch on 4.1 . I have tried for a week or so to get it jailbroken, finally found out i was using the wrong version of redsn0w. So i finally Jb'd the thing and now the cydia icon is white, it wont load anything with cydia and safari or the app store wont load. i know my wifi is working cause it worked just before i jb'd. i get the error:

Method http has died unexpectedly!
