There's one surefire way to solve the iPhone 4 antenna problem: don't let your hand or fingers come in contact with its metal band.
Easier said than done, right? Unless you're willing to constantly use the speakerphone, a headset, or a pair of gloves, your only viable option is to keep the iPhone in a case--or, as some have discovered, wrap it in a rubber "bumper."
iPhone Guru blogger Oliver Nelson crafted a clever DIY iPhone 4 bumper solution out of one of those rubber wristbands you probably have sitting in a junk drawer.
It's a pretty straightforward project: stretch a wristband around the edge of your iPhone and presto, you're done. If you're handy with an X-Acto knife, you can cut holes for the headphone jack, mute switch, dock connector, and so on.
Neat, but does it work? Says Nelson: "My reception is substantially better after having wrapped my new iPhone in this ugly but functional abomination."
Ugly? I dunno, I think these neon colors look pretty spiffy framing the iPhone, at least in Nelson's photos.
Alas, though I have a whole basket of these wristbands sitting right here, I don't have an iPhone 4 on which to test-stretch one. If you're able to put this cheap, clever solution to the test, hit the comments and let me know how it fares.
