After a few hours playing with Mango, and using the "voice" features in the car; here's my concerns....
1) Even at volume "30", the "Voice" of the phone isn't very loud unless you've got an earpiece in.
2) Texting with voice is really hard if you've got an accent from "true" english.... It takes several attempts for the phone to "think" what you've said... i.e I say "arrive" it comes up with "try"
3) The Bing Maps "turn by turn" doesn't work! Having to tap the screen while driving to see what's happening next isn't really acceptable.... So I hope there's an improvement on this to stop me from using third party GPS apps
4) Chat - In the "Online" area of the "Messaging" should display what the person is on/using and not just "available"
Other than the points above, Mango is a vast improvement from the previous updates!
I love all the other features, I just hope it's a bit more polished and ties all our loose ends off prior launch!
Bit off topic, but have they announced the actual release date of Mango?
