It's been said, but coming from many years with RIM devices, it's nice to have a browser that actually works.
^^ Absolutely 1,000,000 % agree ^^
From my previously Blackberry (Storm1 and Storm2), I just about gave up using the browser. It was soooooooo slowwwwwww and very difficult to use - zooming in and out of a webpage was not an easy task - ask anybody who had a BB Storm! Some webpages did not load at all.
iPhone 4 browser / Safari = WOW, WOW, WOW, WOW !!!!!!!!!!!!!!!!!!!! It's incredible !!!!!!
EDIT: Also on Blackberry, I constantly got "truncated emails due to size" messages and haven't had one of those yet on iPhone. Anyone know if the iPhone "truncates" messages if over a certain size??
