I work for a heavily heavily regulated financial services company.  All of our computers, mobile devices, etc. are totally locked down to prevent insider trading.  Thus, I cannot install any apps on the Blackberrry.

Until recently, maps.google.com on blackberry worked, because everything was done on google's server, and the server sent HTML to the blackberry ready to be rendered on the screen.  However, very recently (March 2012), I go to maps.google.com, and I get "Install Now version 4.5.3"  Can't do it.

How do I get back to a server-based Google maps, with no app on blackberry?
