iPhone & iTouch Safari different?

Just went to http://mundu.com/im/iphone/ with my iTouch and it says that there's a difference between the iPhone Safari and iTouch's.

This is a web based IM program.

I've been reading reports of the Touch not being able to access iPhone ready sites. Probably has to do with the way Safari on the Touch identifies itself in contrast to Safari on the iPhone.

Mine said the same on my touch.

when I visit my website and then go to statcounter, all statcounter reports is:
Browser Safari 1.2
Operating System
Resolution Unknown
Javascript Enabled

I played with a touch for the first time today. I used a Touch and iPhone in the same store, but it seemed like the iPhone web pages loaded noticeably faster.

found an IM program that works jivetalk for iphone. Sorry can't link i'm on my iTouch right now
