My application is for "iPhone ONLY", But I have made a mistake in the first place by not setting the application for specific device. The current setting now is: Requirement: Compatible for iPhone, iPod touch and iPad. I would like to set it to: Requirement: Compatible for iPhone. I have go to some tutorial and forum. and nothing can solve my problem. I have also contact the apple support and this is what I got: "You are permitted to expand your device requirements only. Submitting an update to your binary to restrict your device requirements is not permitted. " is it mean that I can not set my application for iPhone only? If i can change it, what would you recommend me to do? I have change the setting of device capability inside the plist, to one of this. which one is correct, use "UIRequiredDeviceCapabilities" or "Required device capabilities"? i provide the screenshoot in here: http://img218.imageshack.us/gal.php?g=screenshot20100604atam1.png does the way I use it correct? Thanks.
