I was just pondering this idea after the announcement of the new 3G iPhone and I'd like to know if this is a good/bad idea. I currently have an iPod Touch 16Gb which I bought for $400 and it's great, but there's some features missing that I want. The biggest feature is the speaker. I'd love to listen to music w/o using headphones and it makes showing friends a song much more convenient. In addition, there's some other stuff that the iPod doesn't have but want; such as the volume rocker and camera. So I was thinking that I should sell my iPod Touch and get either the 8 or 16 gb iPhone w/o the phone plan and use it just like an iPod. Bad idea?
