Re: Something for the kiddies
"I have never even considered that it was even possible to connect directly to an Exchange server from a BB terminal.."
Yes it is, and a whole load of other email server types too. Mine's bolted onto Hotmail (or whatever it's called these days) too.
Plus, BB Balance allows you to do a neat trick. The phone implements a Multi-Level Security System, and I've had to do a lot of reading to glean what follows from that. [Alas I've not got a company phone, nor my own BES, so I've not been able to try it out myself]
So, as I understand it, one level is "personal", and can be joined to your own email, Exchange, Facebook, Twitter, and can have it's own apps, calendars, contacts, the lot.
The other level is "company", and is joined to your company's BES server, has its own email, apps, calendars, contacts, the lot. The company has full control of that level, they can install apps, setup email, wipe data remotely.
The clever bit is that nothing in the company level can be interact with the personal level, nor can anything from the personal level interact with the company level. Personal apps can't nick company data. Company apps can't see personal data. That provides assurance to the company that their data is safe, but you can still do your own personal thing knowing that your boss can't see. The company can even remote wipe their level in the phone, but they can't touch the personal level at all.
And the really clever bit is that apps like the Calendar and Contacts sit above both levels and can see down into them. For example, that means that you can see both your company and personal calendar when arranging a meeting, but your company can't see your personal calendar at all.
What's more, all that's got some pretty good approvals from various bits of the US and UK governments. That probably means that it's quite strong (though of course recent events might have dented that inference somewhat...).
You need Z10, Q10 and so on to be able to do all this; older Blackberries won't, and I think that the company needs to upgrade to the latest BES too. There might be money involved in doing all that, which might put off a company from upgrading.
It'd be interesting to know if your company has heard of BB Balance.
