It appears that the iPhone 4S and the iPad 2 no longer use the chip set that forms the basis for the present litigation, so they are not affected (Apple presumably will be absolutely devastated at being forced to only sell their high end models).
I see. Do you think it would affect its price on the market?
It shouldn't. The numbers show that Apple 4S business outstrips their previous generation model sales by insane amounts, something like 80% of iPhones sold are 4S models.
The tiers aren't as important to their success as people make them out to be.
