But a cheaper and easier way to get an iPhone that works on T-Mobile, etc. is to buy an old iPhone from an upgrader for $100, maybe even $150?
This week: you might actually break even or turn a small profit from selling your old iPhone on eBay or craigslist. A quick search reveals that used & unlocked 8Gb iPhones are going for ~$400 and 16Gb for upwards of $500, with never-opened phones going for even more. Here are some recent old iPhone auctions:
Before the announcement of the iPhone 3G, new 8Gb iPhones retailed for $399, 16Gb for $499. When the iPhone 3G comes out on July 11, the supply of old iPhones in the marketplace will greatly increase (which means that the price will drop) but the auctions above suggest that those old phones might not be shiny paperweights after all.
