I updated my iPhone to 1.1.3 from 1.2 using ZiPhone and everthing worked well except it has left me with a whopping great chunk of my memory being used up. I get the feeling that maybe its backed my iPhone up first and put it to one side, just left it there. When it had completed, all my sms messages were still there and 'Notes' etc which I was suprised about as I thought they would have gone with the update.

I have since upgraded to 1.1.4 using iNdependence to see if that would clear it but no joy. Does anyone know how to clear this or had similar problems?
