Here's an interesting issue. I was going through iTunes deleting apps so I could have room for RAW photos being sent to my phone during an event in a few weeks. I'd cleared out a few large file-sized apps and only had a few remaining. I looked at the apps that had information inside of them that wasn't "part of the app" according to iTunes. Knocked down the free space a few more gigabytes. I accidentally clicked EyeFi and saw the used space jump down by 2GB's.
I was baffled. How can a 2.7 MEGABYTE application which sends the photos directly to the device camera roll, consume 2.1 GIGABYTES of space? Below is a video of the issue.
