One of my daughter's friends had an entry on his blog this week that his SIM card had gotten fried and he'd lost all his contacts. I've worried about the same thing. My SonyEricsson T616 has infrared so I've tried beaming my contacts back and forth between my trusty ThinkPad and the phone. The phone creates and accepts .vcf format but you have to do it one contact at a time. (Actually, the phone will let you "send all" but I can't get Outlook to separate them.)
Anyway, while doing my morning blog reading, I came across this on Gizmodo.
It comes with software to copy the information from the SIM and to manage the PIN as well.
