You can’t buy one without a plan I do not think. Which means you have to checked for unlocked ones on ebay. Although if the phone is unlocked you could just use it on any network. Might as well get an unlocked one and have it replace your cell
Well, I just upgraded froman original iPhone to a 3Gs. I switched my number to the new phone. Much to my surprise my old phone works perfectly over WiFi- no Edge/telephone. I can email, Fbook(using the app) etc if there is wireless.
I use my iPhone on Wi-Fi whenever posssible, especially at home. It’s faster than At&T’s 3G network (for mine, anyway, it’s not the 3G S) and Wi-Fi gives you twice as much time on a battery charge.
There are rumors that the third gen Ipod touch (probably due out September) will have a camera, and I think microphones are already possible through certain headsets.
Like IvoryTowerDenizen, when I upgraded my old iPhone I turned it into what was, essentially, an IPod touch. However, I didn’t have an issue with buying it used from some other person. AT&T just suspended service on it and it was good to go as a phoneless device with Wifi and all the other goodies.
I don’t know how complicated it is to get a Simcard as Declan describes.
