Well I finally moved into the current century from nextel. And so far I am pleased as punch about my 8300! I love the BB Maps with realtime GPS, e-mail, Facebook, and MP3 player, all for $60 a month? And the accessories that came with my phone makes the $249 I paid worth

it and more!
But I have a few questions/problems.
How can I get the GPS BB map to show directions on the map? it shows the first line of directions but does not update as I move along the purple line?
And when I put my phone on silent in the top right hand corner (for meetings and such) it still rings! And when I go into the menu to put it on silent it still notifies me with a sound when I receive a text!
Is there a way to put it on vibrate/silent mode easily? My nextel had a volume button on the side I would just turn all the way down until it vibrated, then I knew I was safe in a meeting/class.
Thanks for any help with these matters in advance!
