app install failures but takes up space.

I tried installing KOTR with two diffrent IPA installers witch both seemed to fail so i gave up and uninstalled them then I noticed I only had 1.5g free from the 6.58g before I tried installing KOTR. Well when i uninstalled the IPA installers it re-springed and KOTR was there so i checked the usage in the settings and KOTR is 1.8g but its taking up 2.5g. so is there any way i can get the 4.78g back.

As in trying to use an alternate means to install a pirated copy of the app??

Here's how to fix that... restore your iOS to stock... then re-jailbreak if you're into that... then don't pirate software in the future to avoid similar issues.

iMore does not aid, abet or condone piracy...
