Consumer Reports has retracted an earlier recommendation to buy the iPhone 4 after testing the device.
When your finger or hand touches a spot on the phone's lower left side - an easy thing, especially for lefties - the signal can significantly degrade enough to cause you to lose your connection altogether if you're in an area with a weak signal. Due to this problem, we can't recommend the iPhone 4.
They conducted tests in a radio frequency (RF) isolation chamber to confirm the hardware issue.
We reached this conclusion after testing all three of our iPhone 4s (purchased at three separate retailers in the New York area) in the controlled environment of CU's radio frequency (RF) isolation chamber. In this room, which is impervious to outside radio signals, our test engineers connected the phones to our base-station emulator, a device that simulates carrier cell towers. We also tested several other AT&T phones the same way, including the iPhone 3G S and the Palm Pre. None of those phones had the signal-loss problems of the iPhone 4.
