I cancelled a sync whilst I was syncing a 2.1 GB app to my iPhone. However, the bar along the bottom of iTunes now states 'Other' is at 2.2 GB, whereby it wasn't anywhere near that size before. The app doesn't appear installed anywhere on the iPhone. I have removed all references of the app from iTunes, still no luck. I have a jailbroken iPhone and DiskAid. Where should I look to search and destroy this file?
