CNET News Video: iPhone 4 bumper test

1:59 /

Do Apple's bumper cases fix the call quality issues that result from touching the iPhone 4's antenna? CNET takes an iPhone 4 and a bumper into the field to find out.

-Hi, I'm Kent German, Senior Editor for cnet.com. A few weeks ago, we showed you how the iPhone 4 call quality can degrade when you touch that trouble spot on the antenna on the left side. Now, since then, few of you have asked us if the bumper, which Apple is now giving away free, actually solves that problem. Indeed, in our test, we have found that the bumper takes away any call quality issues. But we wanna show you for yourself. So, what I've done is I've called way up there to the CNET studio---- Yeah, call landline. I'm gonna run through a call, count to 10 a few times, then, put the bumper on, and then see if we have any changes. Well, first we're start up and not to touch that area, count to 10: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 [unk] and keep it in that area. Start up though without a [unk]: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. And I'm gonna take my hand and put it in that [unk]: 1, 2, 7, 8, 9, 10. And now, I'm just gonna hang up the call, I'm gonna put on the bumper, and then we'll just call back. Okay, oops! There you go. I gotta snap it on all the way. Okay, I'm calling back now. -Hi, Kent! -1, 2, 3, 4, 5, 6, 7, 8, 9, 10. Okay? -Hey, there you go. You can see there is a distinct difference between putting out that bumper and leave it off. So, we're very glad Apple is giving them away. I'm Kent German for cnet.com.
