Some of you may be aware of iMtG, which is a mtg toolbox app on iPhone, iPad and iPod Touch. With the newest version 3.2 I added a test integration with deckbox.org based on CSV. You should be able to enter Gathering in iMtG, then go to Announcements where I started deckbox.org thread with more info. Basically, you try to export your stuff from here (Inventory/Tradelist/Wishlist -> View -> Export) and iMtG should load it as Magic Binder. Magic Binders can be then emailed out of iMtG as CSV files.
