So how exactly can I use the current 2 pin socket for a cigar lighter?
Just buy a 2 pin plug, connect it in then solder to the cigarette charger therefore not ruining the old socket its self and making it easy to just unplug?
I am not after a permanent thing, only for ipod and satnavs on longer journeys.

I wouldn't recommend that as the old socket isn't polarised - ie. there's nothing to stop you plugging it in the wrong way round and killing the sat-nav etc. It wouldn't matter if you were just plugging a lamp in but electronics don't like reverse polarity. I would just wire a new multi-way socket back to the fusebox via an inline fuse in the engine bay.

Fair point that, even if you marked the positive pin on plug and socket, its not foolproof on a dark night. Prob best to permantently wire in a multisocket adapter as suggested. I have one in my van, which just sits on the parcel shelf and is fed from a convenient ignition supply behind the dash.
