Not sure why you want to do it but you can do 2 things. Go to browser/options/browser configuration and scroll down to emulation mode. change it to microsoft IE. Hit the back key and save. Then go to browser/options/cache operations and clear history. If you want to change it back to blackberry emulation you just go back there and change it then go to browser/options/cahe operations and clear your hiistory or it will still emulate as IE. Secondly you could use Opera mini since it will work faster than using the blackbbery browser emulating as IE. Get it here www.mini.opera.com.
