iOS 6 Available Starting September 19
pushing iOS 6 to a 3GS?
Even iOS 5 did not sufficiently cripple the 3GS to stop people form buying them new from AT&T on contract, or from throwing out their old one that they updated. Thus, I suspect that anyone who updates their 3GS to iOS 6 will, very shortly afterward, immediately be in the market for a new iPhone, and not a 3GS (no longer available)!
Apple Maps?
If iPhones existed in their own little universe, seperate from all other phones,
As it stands alot of these features were already offered by other phones for quite some time, and most if not all are already available on previous iPhones through third party apps.
Still, for people that like iOS, it looks to be a pretty good little device.
