Same ish. My itunes says that my ipad is 3.35 gigs over capacity which i dont even know how that would happen, because it stops when it hits capacity and says "you are out of space", i don't even know how 3.35 gigs of information could get past the amount of space on the ipad (ipad2 btw).
the last time i loaded about 100 comics on and that maybe took up 2 gigs, this time, i started off by deleting 50 or so comics, then cleaning out my photos and getting rid of some apps and tried to load about 80 comics and its telling me all this storage full nonsense so i'm thinking it may be a similar problem to what is being discussed here.
Hey, I have the same problem on my Ipad. Power off and on again didn't solve anything :(
The only way would be to delete and reinstall Comic Zeal app, meaning I'll have to re-import all the comics already imported.
