In the words of McEnroe: "You cannot be serious!!!!"
$2.99 for the full version? You can buy a calculator for half that price... And $0.99 for the lite version?
I wonder if there is a table out there that keeps track of the price per line of code... Because I have a feeling you must be up there with the best of them.
Seriously. For $0.99 you can download sophisticated games, advanced document readers/managers, etc. Thousands of lines of code. And you want people to pay $2.99 because you bought "My first iPhone application" on Amazon?
I suppose if you were daft enough to try and promote your app by pretending to start a thread for interesting iPhone apps, I shouldn't expect too much...
