So if you have managed to upgrade to the iPhone 3GS you may be considering selling on your old iPhone 3G, and obviously you want a good price for it. Well Cnet has done some checking on what the iPhone 3G can go for.
For instance, a 16GB iPhone 3G on Craigslist and eBay shows that the going rate for an ?mint condition? iPhone 3G is about $400, so it doesn?t take a genius to realise that if you pay the $200 for an iPhone 3GS and sell your iPhone 3G for $400 you end up $200 in profit.
There is also selling you iPhone 3G on to a service such as Rapid Repair who have a program running whereby they will buyback an 8GB iPhone 3G for $230, a 16GB for $270 and even pay shipping costs.
