Rather than posting again; will the 4S suffer from the same "you're holding it wrong" antenna issues? I haven't personally experienced it, but it has been bumpered since new. The question is, if it will, will Apple release the same "free bumper" App as they did last year?
Apple has
changed the antenna in the new iPhone 4S so that the cellular radio in the phone can choose between two antennas, depending on which one is sending or receiving signal best. These two antennas are part of the stainless steel band that wraps around the sides of the iPhone 4 and the new 4S. On the iPhone 4 this band is split up into several antennas so that one piece does Wi-Fi, another does GPS, another does Bluetooth and still another does cellular.
But on the new iPhone 4S, the (GSM) cellular antenna is divided up into two pieces. So if you apply
the death grip to attenuate to one piece of the cellular antenna, the radio will, in theory, switch to the other piece that isn't being gripped. So you'll have have to apply a
Double Death Grip squelch off cellular service to the new phone completely. That move is usually seen only on Star Trek and in pro wrestling rings
