Wirelessly posted By lifespan I mean how long will it be able to run the latest version of iOS? I figure it has to be at least the same as the iPhone 4S since they have the same CPU, GPU, and RAM, and the 4S has a lower clock speed. Assuming Apple continues offering 3 iPhones, the 4S should be around a while. This fall it will be the "middle" phone, and next yr (fall 2013) the "bottom" phone. If that's the case it should be able to run iOS 7 until iOS 8 comes out (assuming fall 2014). Just trying to figure out what the lifespan would be since I'm thinking of buying a refurb iPad 2. I think from now it's about 2.5 yrs. Would appreciate any thoughts though.
