There are some intranet scripts from work that the blackberry browser can deal with it. From experience on my personal phone I know there is a chance than an aftermarket browser (bolt, miniopra, etc) might do a better job. I tried bolt but it won't. It tells me the name of the website could not be resolved by the dns server which should be the case because it is an intranet server so bolt needs to connect to the intranet dns servers. I can browse the internet with bolt with no problems.
