On November 2 we submitted IM+ v.3.5 to Apple Review (see change log at viewtopic.php?f=3&t=30)
Today we have received a reply:
"Unfortunately, your application, IM+ 3.5, cannot be submitted to the App Store because it uses a standard ContactAdd button for an action which is not its intended purpose. Applications must adhere to the iPhone Human Interface Guidelines as outlined in the iPhone Developer Program License Agreement section 3.3.5.
The ContactAdd button is to be used to display a people picker to add a contact to an item. Implementing standard buttons to perform other tasks will lead to user confusion. It would be appropriate to use a custom icon."
