So I upgraded to 4.1 last night and have just one issue. Prior to the upgrade I purchased Pkgbackup which worked great except for the fact that each of my apps from Cydia are just a blank icon. They each have the correct name under it and they all work but the icon itself is grey/white. I have already rerun the restore and also rebooted my device (iPhone 4). I also used a restore before the last one (done 15 minutes earlier) and it produced the same results. Help?
