Application not working

I have been waiting for the application to be launched on iphone, received an email and bought it but it will not work on my iphone 3.0 version, what a tragedy, Now I have to ask apple/tarascon to refund my money I dont know how long it will take. When click on tarascon support it says requirement iphone 3.0 or higher but it is not working for me. no other help available.
