Hello Yuki,
Thank you for your interest in BookBook for iPhone5!
Although I can assure you that we have started designing a BookBook for iPhone 5, it is too soon for us to make any predictions about its design or when it will be available - there are simply too many unforeseen changes that could occur in the development, manufacturing, and shipping phases, and we never want to make promises we can't keep.
Since we cannot reliably predict what Apple may offer before they actually make their announcements, we always have to wait to start production. Once we actually get our hands on their new devices, we can start manufacturing our products to support theirs. And since we want our products to be perfect in fit and performance, were never first to market, but were usually one of the best once we arrive.
I wish I could be more informative, but please know that we'll work as hard as we can to get the best possible product to you as quickly as we can.
If youd like us to send you any news regarding our products and compatibility with the iPhone5, please sign up using the link below. You'll only receive emails when we have something significant to announce to iPhone5 users and you can opt out any time. The link is below for your convenience.
