For the BB browser issue open the browser, select options then go to browser configuration and make sure your default browser is set to 'internet browser'. Also try my settings, check support html tables,set show images on to ' wml & html' pages, set emulation mode to blackberry and then set content mode to wml & html.
See if that makes a difference to the BBbrowser when clicking on links.
I haven't had opera for long so I cannot really help you with that.
Let us know if this works for you.
