According to Consumer Reports, the iPhone 4 on Verizon Wireless’ network has a similar problem to the AT&T version. If the phone is held in a certain way, it could cause dropped calls or problems dialing out. This is due to blocking of the antenna which is in the band around the phone.
Consumer Reports tested the Verizon iPhone 4 and found that covering tiny gaps in the metal band surrounding the phone’s edge causes “meaningful decline in performance.”
In conditions where cell signal is weak, the iPhone 4 would drop calls when the user covered the gaps by holding the phone in a specific — but natural — way. This issue can also be avoided by using a cover on the phone which prevents contact with the antenna.
Consumer Reports conducted similar tests last summer on the iPhone 4 that runs on AT&T Inc.’s networks. In both cases, the publication has decided not to include the phone on its list of recommended smart phones.
