I recommend checking out the SquareSpace iPhone app for some ideas. You can sign up for a free account at squarespace.com for 14 days. The iPhone app will give you a great idea of what features people are using and how you might implement them. I’m not saying it’s perfect, especially on the backend, but it’s pretty slick.
Very surprised this thread has gone so cold! Mobile is growing at a ridiculous rate and we have to change to accommodate. Has anyone come up with an actual solution to this? I'm aware of Handyman, but find it kind of lacking, to be honest. Also, it seems that development has kind of stalled on it.
