I have a very simple free iphone app that has been rejected by the app store because here is their statement;
"When the device is not connected to a network, your app does not load its contents and stays blank. This behavior might lead to user confusion. It would be appropriate to display either a notification or an alert stating that internet connectivity is required."
In addition I already have codes that can detect wifi connectivity but need someone to just add the code into my app. Should take just a few minutes of work to add the code, if you understand iphone development.
