Regarding the iOS / Amazon Releases:
Hello all, we're terribly sorry to be so long in coming with this update, but truth is that even after taking the extra time we can't say anything concrete yet.
The long and short of it is that we've run into unexpected difficulties outside of our control with the iOS release in particular, and while we haven't given up trying to resolve them, neither are we in a position to put a date on the iOS release. The release for Amazon/Kindle is likewise being looked into.
We will update you again when we have concrete information, and we're very grateful for your interest and your continued patience.
