My friend has an iPhone 3g 8gb that he never uses and I have a jailbroken iPod Touch 2g 8gb that has a lot of nice features. My friend and I want to trade our devices and he said he wants $25 and my iPod Touch for only his iPhone. Is this a good deal for me? I don't know because I've done a lot of work on my iPod Touch so I think just trading the iPod touch and the iPhone is a fair deal. What do you think I should do or is a good amount of money to give him with my iPod touch?
