In order to even compose your message in this ad "supported" version the developer has decided to force you to click on an iAd.
To the developer: if youre that opposed to offering a free version of your app then just dont offer it. If you do offer a free version dont force people to click on ads. Its very dishonest, not to mention very passé. If people like the product enough they will buy your paid version.
As it is, I trashed the app right when it said "click ad to continue."
