Okay this should be in the "Non Universal Binaries" section, but I didn't see one, so bear with me.
I have an app that has some different interface functionality depending on if it's an iPhone (small screen) or an iPad (big screen) and I am going to release the two versions as separate apps (business decision, please don't attack me for it). Since there is no reasonable way to block an iPhone only app from running on the iPad (compatibility mode) I'd like to know when someone is running the iPhone version and have the app show the appropriate interface.
Suggestions?
