Although the iPhone 4 was well received after its initial launch, many complaints arose regarding its antenna, with many claiming that the iPhone 4 had a “death grip” antenna problem, in which significant signal drop occurred when holding the device in a natural way. Fortunately, MacRumors reports that the iPhone 4S has now repaired this issue.
When held in the same manner that produced the “death grip” in the iPhone 4, the iPhone 4S experiences no signal loss at all, while the iPhone 4 had been known to drop two or three bars.
