There are issues about the iPhone 4, but the biggest issue is the poor signal reception when the phone is held in normal way it covered the antenna and can even caused a call drop. Costumer Reports Lab test on iPhone 4 shows that the phone is hardware defective rather than software.
The Consumer Reports test four iPhone 4 by holding it in many ways and using a base station emulator which acts like one of AT&T’s cell phone towers to send signal to the phones.
It is resulted “Our engineers found that when you place your finger on the gap between the two antennas on the lower left hand side of the iPhone 4, signal strength can drop by about 20 decibels and that’s enough to drop a call”
The test is run on normal AT&T’s wireless network on controlled area where no other phones are connected except the four that has been tested. Now that it is truly a hardware problem not a software problem like the Steve Jobs’ had mention, the Consumer Reports is not recommend the iPhone 4 to the costumer.
