Is there anyway to release an universal app but prevent iPhone 3GS users from purchasing and installing it? Our game doesn't work very well in lower resolutions but run fine on iPhone 4 and above, as well as iPad 1. Would be a shame to block all iPhone users just because of a device that maybe 5% will be using, but on the other hand I don't want to risk people paying for something that is pretty much unusable and leave bad reviews...
Leave big warning signs that say don't not download on this device or write apple the description I believe

Cheers. You can't change the description based on device though right, it would just have to be a warning that is visible for everyone?
That's right. You just have to say that while it is compatible for all devices, the app may not run as well on the older ones (i.e. iPhone 3GS).
