As far as I can tell, there aren't any "performance" criteria that you can specify to exclude specific iOS devices via info.plist.
Is it possible, via info.plist, to allow a universal app to run on iPad1, but not on iPhone 3GS/3G? Right now I use the gyroscope requirement (which my app does make use of), as a crutch to support only iPhone 4+ and iPad 2+.
To be absolutely clear, I want to make the app AVAILABLE FOR DOWNLOAD in the App Store on iPad1, but not on iPhone 3GS. This question is not about runtime query of the device from code.
Is my best/only option to create multiple binaries, and remove the gyroscope build from the iPad build (typically called the "HD" build) but leave it there for iPhone/iPod touch?
Look at this question:
Determine device (iPhone, iPod Touch) with iPhone SDK
It goes over determination of different iOS devices. So, you can explicitly support (or not support) some specific model.
Requiring armv7 will drop out everything <3gs, but still includes ipad1. That's the closest I see.
The short answer seems to be "no".
On the up-side, iPad1 only has 256Mb memory, so you need to make your app fit in 256Mb anyway, so it should work on the 3GS. The difference in CPU speed is significant though.

I'm want to target the iPhone 4, iPhone 4S, iPod Touch (4th generation). I do not want to target the iPhone 3G and iPhone 3GS. I've seen some post that said this is not possible. However, I notice in the App Store that some apps do this such as the picture below.
How would I accomplish this?
Those requirements show up because the developers have put armv7 as an entry in the UIRequiredDeviceCapabilities Info.plist key. There's no key specifically to target the iPhone 4 and up, although you can probably eliminate the 3GS using one of the other keys.
Why are you trying to stop people from installing your app on older devices?
I believe you want to set UIRequiredDeviceCapabilities to specify exactly which features your app needs. For example, the camera-flash key is only going to be true for iPhone4 and later, if that's what you need.
There's also a Q&A article on it.
In addition to setting the features the device needs with UIRequiredDeviceCapabilities, you can also specify the minimum iOS version that needs to be installed.
See this Apple Technical Note, TN2250.
How does one remove the iphone 3G and the ipod touch 3 from the target?
I have an app that uses libraries that need armv6, so cannot remove that from the architectures. Is it possible to still exclude the iphone 3G and the ipod touch 3?
Thanks
NB: I've assumed you also don't wish to include devices lower than those that you've specified, i.e. ipod2.
It's not possible to remove devices individually from your application, but it is possible to restrict what your application requires in an attempt to restrict devices.
I can't think of anything that works exactly if you need to maintain armv6, but if you can think of something that the devices you want to include have that the devices you want to exclude haven't, you can add those items to the Required Device Capabilities in your Info.plist.
Open-GLES 2.0 might be a good starter think to require as the iPhone 3G has Open-GLES 1.1.
If you tell us a little more about why you want to exclude these devices, I might be able to provide a more elaborate answer.
I have an app which runs excellently on an iPhone 4, and comfortably on a 3GS. Is it possible to target only the 3GS/4 and not the 3G? The 3G just freaks out when I run it, all sorts of graphical glitches, crashing, low fps etc, I don't even want 3G users to see the app on the store. I can't really 'tone down' the app to use less memory/power for the 3G, it would remove the main purpose of the app.
The only way I have come up with is to adding multitasking as a requirement for the app in the info.plist, but this seems a little hacky.
Also, is this likely to get me in trouble as far as submission goes?
Add "armv7" to the required device capabilities of your app's info.plist. Only the 3GS and newer use that CPU architecture. An app requiring armv7 won't even install on a 3G and other older armv6 devices.
Looks like this has been addressed previously, you can determine the version and perform an appropriate action based on that.

I'm shipping two binaries; one for iPhone/iTouch and the other for iPad. It's the same application.
Will Apple ensure that the user will never receive an iPhone version of the app on the iPad? If YES, then I don't have anything to worry about, but if not then I do have a problem.
The reason I ask is the iPhone application will simply not work correctly on the iPad because the server knows it's an iPad and will deliver the iPad HD content to it and the iPhone cannot handle that. I would rather not hack my application to send the server a fake device type if running the iPhone app on the iPad in order to receive the correct resources.
Suggestions?
I've been looking for this for a while because I couldn't prevent the iPhone app to load on the iPad. Searched a bit to understand why this was happening, followed #hotpaw2 instructions and found this on the official apple store rules:
UPDATE:
2.4.1 To ensure people get the most out of your app, iPhone apps should run on iPad whenever possible. We encourage you to consider
building universal apps so customers can use them on all of their
devices. Learn more about Universal apps.
https://developer.apple.com/app-store/review/guidelines/
The SDK and/or App store rules prohibit you from preventing an iPhone app from running on an iPad in 1X or 2X zoom mode, unless there are other requirements listed in the app plist. Apple's app review is known to test iPhone-only app submissions (unless there are other requirements) on an iPad, and reject the app if it doesn't run properly.
Other requirements (as listed under UIRequiredDeviceCapabilities in the app's plist) might include your app requiring telephone capabilities (or healthkit, etc.), which might help you temporarily, but still won't prevent the app from running on some hypothetical future iPad product that includes telephony capabilities (and/or healthkit, etc.).
Actually you can.
Add telephony to UIRequiredDeviceCapabilities in your plist file.
But i really not recommend it and maybe you could get rejected because of gratuitously using this property.
I think you should handle that there are iPad versions and iPhone versions on iPads, use the second one as an iPhone.
Also don't forget that retina iPads will use upscaled applications at retina resolution while none retina ones use the standard resolution. And this behavior can tweaked using jailbreak tweaks like RetinaPad and FullForce.
In the plist settings, add Application requires iPhone environment and set the boolean to YES
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.

Make it run better. Or if it's not completely unusable, just let them use it anyway. People with old devices expect them to be a bit slow.
According to the iTunes Connect Developer Guide (which links to the iOS Application Programming Guide), you can't prohibit certain devices. You can, however, require certain features which are only present on new devices:
armv7 is what I'd recommend (older devices are armv6)
magnetometer, because older devices don't have one. Apple might look at you funny if your app doesn't actually use the compass though.
opengles-2, because older devices only support 1.1. Apple might look at you funny too.
auto-focus-camera, except the iPad and all the iPod Touches don't have one. Probably not what you want.
iPhone 3GS uses iOS 6.1.x so if your app support iOS 7+ it will not be able to install on iPhone 3GS, this is the best possible way to avoid download on that device.
