Sony Ericsson Z520A. It's a great phone with excellent reception and battery life, plus camera and bluetooth. Built in media player doesn't hurt - though it's not a true mp3 player, like some others.
Motorola v557 - camera, bluetooth, and a Motorola... or...
If you want to save money, a v551. Exactly the same phone with slightly older software (hence a dropped call here or there, though not many), and no "live ticker." So... who cares? These can be had relatively cheap these days off of ebay, even new.
Those are the three that come to mind. I sell more v557s and Z520As than anything else. If you have any questions about them, let me know. (Probably in a PM, because I have a tendency to forget which threads I post in
)
Edit: Forgot to mention: there aren't a lot of inexpensive Nokias that have the features you're looking for. Generally the higher end ones (read: >$400) have bluetooth, but they are also PDAs or have integrated keyboards, which is what makes them more expensive. The lower end ones don't usually.
