The Future of iPhone 3GS
/The iPhone ‘next’ would be the flagship, the iPhone 4S would offer Siri and take the place of the 4 in the pricing lineup, and the 3GS would remain ‘free’ on contract. But, if the prices were right, Apple could expand the 3GS from a contract device to an off-contract pre-paid model that might finally give the company a horse in the developing nations race.
That's a good theory, but I don't understand why it necessitates the death of the iPhone 4.
3GS for Prepaid, 4 for $0, 4S for $99, 5 for $199. Easy and it covers the whole gamut.
