ios - Can I restrict my iPhone app from being used by iPhone3G's?

Question

My iphone app doesn't run well on the iPhone 3G. Can I make it so users with these models can't download the app? If so, what does a 3G user see when they search for my app in the app store?

Does it appear in the store at all for them? If it does, when are they notified that they can't download the app?

I recommend you use the UIRequiredDeviceCapabilities key in your info.plist. This lets you tell the App Store exactly which capabilities you require instead of which device you require. If your app "doesn't run well" on a 3G I'll guess it is because of performance and therefore you'd want to require a newer processor. Look into setting arm7 as one of your required device capabilities.
