I got an iPod Touch 4th Gen. It says I have 1.5 GB remaining; Iron Man 3 - The Official Game is only about 600 or so MB but it says there is not enough room. Why does it say this?
To download and install an app the iPod needs storage available equal to about three times the file download size.
If you sync from your iTunes library less storage available is required.
