Well, we know that Apple is probably just going to call it “iPhone,” kinda like the iPad 3 is just “iPad.” And we’re pretty sure that Apple will not pull another 4S, where the new model is just like the old model, only different.
But will it be curved? Transparent? Taller? Thinner? Wider?
Only Apple knows for sure. Everyone else, however, is having lots of fun trying to predict what the new iPhone will look like. Or what they want it to look like.
