Why is having your email with you all the time is such a problem? I recently lost my ordinary work phone and it was replaced with an HTC Tytn II with Vodaphone Business Email and it's great. Nobody expects an instant response, so if I don't feel like replying until I'm back in the office it's no great problem. If it was urgent they could ring me. Maybe it's just the way different companies work. Or maybe the fact I quite enjoy my job (the practical aspects of it at least).

That said cellphone coverage is patchy where I live so the phone doesn't always work, they've never asked for my landline number.

BTW, my Tytn is completely unlocked (even down to the carrier, my orange sim works in it). I've even got the demo applications from the new Qt/CE 4.4.0 build running on it.
