I have an application developed for iPhone OS 3.+. This application uses in-app purchase.

I would like to release a version now, that it is compatible with 2.+.

Obviously I will have to use that techniques described by Apple that tests for the presence of the frameworks I am using from 3.0 and make alternative code for 2.0, without using those 3.0 frameworks.

my question is: my iPhone is updated to 3.0. How do I test to see for 2.0? Do I need an iPhone that is already using 2.0 or is there anything I can do to simulate this?

thanks for any answer

    Yes, you’ll need a 2.x device. Optionally, you can installed an older version of Xcode on Leopard, and test using the sim, but still, you should always test on a device.
