It wasn’t long after the first iPhone 4 models started shipping that we began to see hardware complaints by the boatload. And nearly all of them were rooted in the same problem: reception. More specifically, when the phone is held, the presence of the human hand at certain points has the tendency to knock out a few bars.
The phenomenon has since come to be lovingly known as the “iPhone 4 death grip.” . Apple CEO Steve Jobs addressed the problem with the helpful advice, “Just avoid holding it that way.” Since then, rumors have surrounded the possibility of a software fix in the next OS update, but the company has otherwise been fairly quite on the issue.
The “death grip” first started surfacing on Apple message boards on June 23. That same day, Apple listed three openings for iPad/iPhone Antenna Engineers. Not sure if anyone can actually wrap their fingers around the iPad, but the iPhone part of the equation certainly seems like too big a coincidence to ignore.
