Have you tested on all hardware models?

If that's difficult, have you tested on all versions of the OS? (2.0, 2.1, 2.2, 2.2.1)

At least, have you tested the release build?

Personally, I had an app whose debug version ran fine but release build crashes. Fortunately Apple caught that.

Then, I had another app which worked fine on my iPhone (3.0 and then I tested in 2.2.1), but crashed on 2.1 and 2.2. Seems to be an Apple threading bug. I wished I tested on earlier OS.

John, thanks for the suggestion. Even though I have tested extensively, I didn't try every OS and I didn't try testing the release build. Since the app writes the default settings to the iPhone, I delete it from the phone before reinstalling/compiling again. I've caught a few bugs this way, but will not try all the OS versions. Thanks again!
