I am having the same issue as bigkopman. I have appsync 3.1.x from sinful, but Cydia keeps trying to install appsync 3.1 from *********. It runs into errors and takes me back to Cydia. Tried to uninstall appsync from sinful, but Cydia tries to install appsync from ********* before it does anything else which causes the errors and takes me back again. I did a search on Cydia for appsync 3.1 from ********* and found it, and it is highlighted in light blue (I'm guessing because it is in Que to be installed). I selected the app, and pressed "modify", then "Clear", trying to remove it from que but it is still there and I can't update anything. I have a 3gs fw 3.1.2
