Not the part that's still on the SD card, the data from the app that's still on my phone. How do I get rid of them? Is the only way to go to the application data in the settings and delete it manually? The data there is named kind of strangely and I'm afraid I'll delete something I don't mean to. If I install an app again, where part of the data from the same app is already on my phone, and part of the data was on the unaccessible SD card, what happens? Will the extra data delete itself or will another copy of the data be made, meaning I'll have excess useless data on my phone?

Thanks for the help.
