The mobile 3 'beta' has been going 8 long months. We hired a new developer for the mobile team a few months the ago. I haven't been willing to sign off on it yet but it's getting very close. I have a new build that looks really good and should be rolling out in the next week or two. The last feature coming out it of beta will be signature.
The one I've been waiting for is quick add. That's in the n3xt build and pulls a Major hole.
