First question: I can't remember but when I retire I'm going toss mine!
Second question: If or when you get your mobile bought and bills paid by your employers you realise it's for a reason.
I had my first company mobile in 1988 complete with hands free kit, since then I've taken literally thousands of calls on hands free, and have never had an accident while making a call, I currently drive around 70,000km a year and just checked my mobile to see that yesterday in one 42 minute trip I spent 23 minutes in calls... I'll let you do the maths!
BTW, I also have a RoSPA Gold drivers and rider certificate, which I recommend as it the training probably gives me an edge in road awareness.
