If you have a free version, then people will measure the cost (money) to the benefit (difference between free and pay versions). Right now we have to pay to 1) get more levels, and 2) have it on the iPhone. If you open up all levels then we lose incentive 1, and only have incentive 2. Same cost, less benefit. Personally, I'd make the app (or website) more shiny. Get a designer (someone else said in your last thread), etc. Maybe have a 5-level demo iPhone version - I've seen that a few times.
