After first insisting the iPhone 4's antenna problems weren't serious, Consumer Reports has completed testing of the iPhone 4 and won't be recommending it to users. While the site lauds the phone for having a great video camera and screen -- their engineers confirmed that nasty attenuation issue that results in dropped signal strength simply by holding the device. The Consumer Reports testing (see video) confirms other recent tests by Anandtech, showing how users in average to poor cell coverage locations are the ones being bitten by the design flaw Apple seems content to pretend doesn't exist. The good news? Consumer Reports notes that the design flaw can be helped with just a little duct tape.
