My BB browser won't open. It takes forever, then I get a message that says the browser is unavailable. Media Net (I'm on AT&T) opens fine and I can access the internet from there (I don't the internet much on my phone yet, mainly check weather and news).
It sounds like you have a media net package and not a blackberry one. (Which is needed to launch the browse. But you siad it worked yesterday. Try resending your service books ?ia the Att bis homepage. And try doing a battery pull.
