One of the more annoying problems with having an iPhone is the buzzing noise that comes out of computer speakers when it gets too close to them. This can be especially problematic given that the most logical place to charge the device for most people is in the same location as the computer so it can be synced quickly, etc. Fortunately someone has found a solution by creating a shield made from some double-sided tape and an empty Red Bull can.<!--break-->

<b>Parts and Tools:</b>
<ul>
<li>an iPhone (duh)</li>
<li>an iPhone dock</li>
<li>1 empty Red Bull can</li>
<li>double-stick tape (he used carpet tape)</li>
<li><em>very</em> sharp scissors, capable of cutting through thin metal</li>
<li>carpenter knife (optional; be careful, and don't use it unless you know what you're doing)</li>
<li>a metal straight edge of some kind</li>
<li>"Patience."</li>
</ul>

Hmm - or you could turn off the speakers :-)

You should only have to shield the bottom plastic part. The metal back of the iPhone is thicker than that Red Bull can. You could probably lean a pack of Orbit gum or a pack of Marlboros behind it and get the same results.:p
