Is the Lightning 8-pin connector magnetic in attachment?
In the external buttons and connectors section of Apple's official spec sheet for the iPhone 5 no mention is made that the lightning connector is magnetic.

Given how proud, and rightly so, Apple is of the MagSafe connector, I'd bet dollars to doughnuts they would mention that the new connector is MagSafe if that was indeed the case.

Secondly, looking at 2D representations of the new connector, it does not have any of the characteristics of the MagSafe connector at all. It uses the traditional male/female plug/socket concept humans find so comforting.

Once I get my new iPhone 5, I'll let you know.
