First-Gen iPhones rise steadily in price

This Business Week article describes the rising demand for first generation iPhones. "Shelf prices" (using eBay values of virtual shelves) for the 16GB iPhone are currently at about $600, and $500 for 8GB models. In other words, the $250 AT&T refurb specials from March are now worth roughly double what you paid for them.

From easy-unlocking to contract-free usage to eco-consumerism, consumers are looking for those original units and paying premium prices to get them. A majority of phones are heading outside the US for resale while growing demand at home keeps resale prices high.
