The design would incorporate mobile and GPS antennas. The problem with the iPhone 4 was reportedly centered around the placement of the antenna around the frame of the phone.
When users would hold their phone to make a call, the antenna would be squeezed, forcing signal reception to drop.
Jobs refused to admit the problem was a design flaw but decided to offer iPhone 4 users free bumper cases to shield the antennas anyway after growing anger.
The patent was filed in June 2009, which means Apple was already working on an alternative to its current design when antennagate occurred. With reports of a new iPhone on the way and set to land on Verizon, the antenna problem could be fixed already.
