I just posted OmniWeb 5.5 Sneaky Peek 3 which includes more browsers in the default list of available options.

As Forrest mentioned, developers should not be looking for "Safari" in user agent strings, but instead "AppleWebKit" since any application can use the same underlying technology that Safari does.

Of course most websites that are doing browser detection look for Safari, and that's why we include the word Safari in our user agent string. That doesn't help everywhere, including apple.com where even they do very browser-specific detection, unfortunately.
