Update August 2018: A small adaptor plate for 8pin cables has been added. This can be put on the cable and fits partly in the 30pin hold to prevent the 8pin connector to fall through. You may need to cut it a bit for perfect fit, but it's thin enough that that should not be a problem.
A wall mount for an iPhone 4 (or 5 with adaptor) in a folding case. There is room left both in the front and back sides of the phone so the front can be folded behind the phone while it's charging.
The plug lives in a hole beneath the phone that holds the plug inside the dock when not in use. When mounted, the plug still fits in the hole beneath the phone so the phone is not standing on the plug as in some other docks -- you pull the plug up from the dock to it insert into the phone manually, before mounting the phone in the dock. This means that you are able to pull the phone out of the dock without disconnecting the plug for that casual look at an app while charging.
