Well, we finally have submitted our CuteTag application to AppStore, but it looks like it would be very hard to save a feature of 256 Encryption ... they requested some kind of licensing, so unfortunatelly, we had to remove that possibility from CuteTag, at least in the first version. Anyway, we will try to add this later... or probably create an Android version, where the submission rules are not so strick.
So, we are expecting to have our application on the AppStore next week... hopefully :)
