Retrieving contacts from phone with broken screen

The screen on my Xenon just died.  For no reason.  I pulled it out of my pocket one afternoon and the screen was dead.  Looked to be shattered on the inside, but no damage on the outside.  Annoying.  The phone is only 4.5 months old and had no physical damage.

So if anyone knows a way to get LG or AT&T to fix the phone for free, that would be great.  But I doubt it will happen.

What I'd really like to be able to do is retrieve my list of contacts from the phone.  They are all in the phone, not on the SIM card.  And I can't use the screen at all to move the contacts to the SIM card.  I've got a microUSB cable and can plug it in to the phone, but I see nothing.  Any software I can use?

Much thanks to anyone who can help me with this!

My wife's was ran over but the touch screen would still respond. I held hers and mine and tapped through in the same spots on both to copy the contacts to the sim card. Best recommendation I can make if it's an option.
