I thought it would be nice to have a thread of items not covered by Apple's guidelines but worthy to know when submitting an App to the App Store.
Any items not covered by the following (login required):
When submitting an live streaming application, a stream less than 64 kbps is required. Also, the live http stream must validate without errors with the mediastreamvalidator so make sure you check before submission.
A free app cannot be feature limited with links to upgrade to the full version. So don't include any links from icons of features not enabled.
