Where to start?
As Crisp said, the fact that council employee's will be walking around with tax payers information on their own personal devices, which as much security as active sync can now give, you can't get it to tell the device to block USB access to every computer but the office machines.
Then there are the unhappy council workers, which realise later rather then sooner that as part of this BYOD, they probably won't be compensated for their own personal phones having to download all their emails and attachments.
To be honest, I don't think any the people who complained about wanting to use their own personal phones for their work emails have realised that it's a bad idea for a bigger reason. By having their work emails connected to their own phones, this means they will make themselves pretty much obtainable 24/7. Yes, alright you can turn your phone off when you leave work...but then what's the point of having a personal phone that you only use in work time? How many people will actually know/be bothered to turn their emails off after 5pm? You might not respond to your emails after 5pm but how many people read their emails when they first come in, just to see if it was something important you were waiting for?
Personally, I think the work phone is the way to go. It's the perfect way of stepping away from your work life and getting on with your personal life because you can turn it off and put it in a draw when you’re on holiday!
Anyone who complains that having to "lug around two mobiles" is a difficult task, man up and stop buying stupid clothes without pockets for work clothes. Phones are not that big and do not weight that much, I’m not asking you to carry around a lead brick in your pocket.
Finally for those who complain that they'd rather have an android or an iphone instead of a blackberry, grow up and be thankful that you've even been given phone for work. My company gave my an iphone (when I’d have rather had a can with a bit of string on the end) but just get over it and work with what your given.
