All right. Don't know what more I can say.
The Apple S upgrades use the same casing with very minor tweaks, if any. I'm talking about things you wouldn't notice unless you open up the device.
I'm not here to argue whether the 4S-to-5 upgrade is good or bad or significant or not; I'm merely pointing out, if the specs of the S4 turn out to be true (larger screen, larger device, slight redesign), it cannot be compared to an S-upgrade. If anything, it's closer to the 4S-to-5 upgrade.
Right. 'Nuff said. With the S upgrades, you couldn't use screen size to see which is which. Just because the supposed S4 and S3 look similar, doesn't mean they are hard to tell apart. The 4 and 4S are much harder to tell apart.
That's all I'll say about that.
