I have an iPhone 3GS and am coming up on my 2 year renewal with AT&T. My DS5 plays games and netflix movies on my iPhone all the time and is constantly drainging my battery. We do have Wifi at home. My DH and I were just discussing the other night that maybe for Christmas we could get him a second hand Touch. But then I started thinking that I might want to upgrade my iPhone, especially if the iPhone 5 comes out in October (as rumored). Would I be able to just use my old iPhone with out the 3G/phone capabilities for DS? I am thinking this would be a big savings for us instead of buying him a Touch.
