I have an iPhone 3GS which has a flaky on/off button.  Before I dump it I want to transfer my contacts to a medium so that I can load them on my next phone which will not be an iPhone.  In theory I should be able to store contacts on the Vodafone SIM card but I can not find a way to do so.  All contacts are in the phone's internal storage.  I proved this by removing the SIM card and restarting the phone without the card

Can anyone offer a suggestion.

TIA
