My palm treo 700wx (windows)

Question

my palm treo 700wx (windows) delivers memory critically low messages and I have nothing but contacts, and not alot of them, on the phone. photos go to a storage card. I can't sync the phone without getting low memory messages, so I can't perform a hard reset without losing the contacts that I've added since my last sync. Alltel tech support is useless. and the phone is out of warranty. any suggestions anyone?
