Move iPhone contacts to SIM

[blehpunk]

I am ebaying my iPhones because I can't afford them until I finish school in the Summer. So we are buying cheap gophone to switch the SIMs over to. Is there a way I can move my iPhone contacts up to the SIM to use on the phones?

I can't find a setting to. I know you can from SIM to phone, but I don't think you can go the other way. Maybe there is a jailbreak app or other app you could use?
