Watchdog publication Consumer Reports has, through its website, announced that it cannot endorse the iPhone 4. The magazine tested three iPhone 4s, bought from three different retailers in the New York area, in a radio frequency isolation chamber where each was made to connect to a simulated celltower. As has been frequently reported and charged in lawsuits, CR confirms that covering the lower left-hand side of the device causes signal to fall by as much as 20dB, enough to drop a call.
