How to improve the connectivity of your iPhone 4 for $1

By now, the solution to the iPhone 4's connectivity problem is clear-putting a rubber bumper around the unit will insulate the antennas that wrap around the phone. Apple itself offers such a bumper for $29 and had given some away to those who waited on line to pick up their phone on June 24th. But as other documents have shown, Apple reps have been told not to promise or give out free bumpers. And considering the price of the phone, why should you be on the hook for another $29 to correct a problem that is not your fault? A better solution has been offered up by one Oliver Nelson. Nelson received a green bracelet like the kind you see cyclists wear, for free when he ordered an iPad charger from crazyondigital.com. However, you should be able to pick up a similar bracelet for about $1 at a hobby store. You then stretch the band around the iPhone and you have a rubber bumper. And to allow space for the charger, Nelson took an unstretched bracelet and made a cut measuring 1.125″ long and about .125″ wide.  He also made other small cutouts for the silent mode toggle switch on the side, and a small hole for the audio jack on top. A little snip here and a little snip there and you have a rubber bumper that costs a small fraction of the $29 that Apple charges.
