I have a 16GB iPhone 3G that I bought in July 2008. Its still in very good condition, save some wear and scratches on the back panel, and I don't have the original head phones anymore. I know I'm getting the new iPhone that will come out in June or July, since my contract will be up and I can get it at the discounted rate. I ideally would like to wait until I actually purchase the new iphone before I sell my iPhone 3G, but am worried it will go way down in value by that time. So I was thinking I could sell it now and just use my old flip phone with my sim card for the next few months until the new one comes out. Do you think the resale value of the iPhone 3G will go way down in value the minute the new iphone ships, or it will be about the same as it is today?
