I uninstalled it (as well as Backgrounder) through cydia as it was slowing things down and I don't seem to use it much. Unfortunatly there is evidence that it is still hanging around in my system. When I double click the home button to bring up the iPod function it shows three buttons and the one that used to but for Pro Switcher is blank but remains. Also the system is slow again. I'm trying to avoid restoring my iPhone.
