Hi ada,

You haven't given many details. Like what exactly the errors, exactly what they say and whatnot. I'm not a Mac user, so I can't help anyway, but that will help you get more responses if you do that. Be very detailed.

And as far as I know, mass storage mode is when the phone is hooked up to your computer, and you want it to appear as an external hard drive to the computer. If that's the case, that's possibly why you're not being able to do voice activated dialing and browse.
