Consumer Reports har kompletterat sitt tidigare test av antennproblemet hos iPhone 4 med ett nytt test där Apples Bumpers används. Inte helt oväntat innebär isolerande plast runt antennen att problemet med sänkt signalstyrka försvinner.

”The Bumper solves the signal-strength problem. So does a piece of duct tape, as we reported earlier, or just being careful how you hold the phone. But these options all put the onus on consumers to solve or pay for a fix. We’re still calling on Apple to provide an acceptable free solution to the iPhone 4’s signal-loss problem.”
