Any way to spoof Safari UserAgent in Opera

[TProUserOnSprint]

There is a new site called http://www.southparkmobile.net that will alow you to watch all South Park episodes through your browser. Basically you select your episode and it opens up a Quicktime stream (I have not been able to find out the stream format) and plays the pisode over the air. If you try opening it on the TP it will tell you that you have to be using either the iPhone or the iPod Touch which leads me to believe that spoofing Safari Mobile's UserAgent would allow you to access the site. The stream would then open up in something like TCPMP.

It works great over WiFi on my iPhone 2G but I'd to be able to watch it on my TP as well using the faster EVDO. This could also be useful for visiting some iPhone formated websites that are very finger friendly.
