Many iPhone 4 users have complained that the signal reception of their phone is not so good. This is perhaps the worst problem which iPhone 4 users experience and is proving to be a big turn off for potential buyers. Apple has built-in a new signal antenna concept in the body of this model where the antenna is believed to be the steel bands at the sides.
According to many, the antenna is on the lower left side of the phone and if that part is covered with a finger or hand while calling, the signal tends to drop significantly causing network problem. Few users have also experienced network problems due to holding the phone in certain angles. Logically this problem is faced by left hand iPhone 4 users because their hand covers the lower left side of the device where the antenna is located.
Steve Jobs had suggested to users to hold the phone in a way that does not cover the antenna. Apparently, Apple also claims that the signal reception problem can be solved by using a silicon bumper case. Hence for all those left handed iPhone 4 users out there, we suggest that you try changing how you hold the phone while calling. Its bound to solve this problem.
