Apple submission requirements for iPhone apps

Im not sure what the implications of point 2.10 of Apples requirements implies. 2.10 states "iPhone apps m开发者_StackOverflow社区ust also run on iPad without modification, at iPhone resolution, and at 2X iPhone 3GS resolution"

If I write an iPhone app that works will it be enough to satisfy this requirement.

Short answer is yes. To make an app work on an iPhone, but not on the iPad you would have to try to limit the features by checking if the device is an iPad and then purposely not working.

If you do not do anything like that, your app will no be rejected based on that requirement.
