An Irritant - in Videos, none of the thumbnails have the name of the vids they represent. Granted, these are not from the Apple Store so I don't know if that's the problem, but this was not an issue in iOS 4 > 6.
An Ongoing - I'm unable to connect to any Contacts via Facetime (via Wi-Fi). It dials out, connects, rings (usually 3 times) and then disconnects. The other side can see this connection and can go to answer it with same result. Others dialing in with same iOS experience same result. A Google shows this has been a long-term issue over a couple of years and there seems to be no definitive solution.
Really, Apple? - Still no ability to add an attachment (other than pic/video) from Mail, not even - noting their paranoia about access to program files - from those you may have in iCloud. Its not brain surgery. Heck even my old Palm TX - the device Apple ripped off (sorry, reverse engineered - sorry, 'reimagined') to create the Touch - allowed for attachments. Shouldn't need to go to a 3rd Party app to do a basic email task
