Since Mike checked out, I'm finding more than I wanted to ever know about the PSP. But since I ran across this, I thought I'd post it.

Adding an External Wi-Fi Antenna to Your PSP

>>Not content with the factory-installed Wi-Fi adapter in his PSP, Seth Fogie added an external antenna to boost his signal strength and improve his signal-to-noise ratio. Here he shows how you can do it, too.
(Then comes lots of text and many pictures.)
>>For only $20 and a little bit of effort you too can modify your own PSP to get these results. However, for all that it may help your signal this mod does severely degrade the aesthetics of your beautifully designed PSP.

Bummer. Aesthetics or quality, but not both.
