Sorry, hope I'm not too late... I have the 8520 Curve and love it. I got a cheap silicon case (£2 ebay) and it's slung in my handbag / rucksack and is very resilient. Piss poor quality pics in low light but I have a digital camera for that. Plus side: easy email functionality, easy to use, apps are all good.
I'd recommend it. But then, you don't know where I live.
Er, didn't mean that in a nasty way or anything, but for an urgent request posting in AIBU/Chat and saying 'Urgent request for anyone who knows about TROMBONES' will work better than just hoping that the curious people who click on 'Urgent request about something but I won't tell you what just yet' happen to know about trombones.
