The iPod dock connector was built in in every iPhone and iPod (except the iPod Shuffle) since 2003. But Apple finally upgraded the port to Lightning for the iPhone 5 at the press conference today.

Even though many things are now done wirelessly thanks to AirPlay, Wi-Fi syncing and other technologies, the connector is still indispensable. Durability was improved, it is reversible and therefore easier to use. But what about all your old accessories?
