Re: Closest to Blackberry Traffic
CoPilot has a traffic subscription that seems to be pretty accurate (in the UK at least).
Best traffic linked satnav I ever had was the Navigon software preloaded on my Nokia 6110 navigator - it had traffic included for no charge. I didn't see traffic jams for a year with that thing. I've not used their Android app but it may be worth a look..
Monkey see, monkey do.
