detecting iPhone app running on iPad in compatibility mode

Question

My iPhone app is not universal but it has a feature that I'd like to enable for people playing on iPads. Is there some way to detect that you're running on an iPad in compatibility mode? The UIDevice methods for detecting machine specs all return the values you would get on an iPhone (on the simulator at least). The only thing I can think of is detecting OS 3.2, but that technique won't work for long.

Reposted since it's so short:

If the app is an iPhone app running in the emulator mode on an iPad, it will have a userInterfaceIdiom of Phone, but a model type of iPad. You can check this with the following code:

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone &&
    [[[UIDevice currentDevice] model] hasPrefix:@"iPad"]) {
    // This app is an iPhone app running on an iPad
}
