is there anyway to tell what smtp address or username or any other useful authentication information (PIN would even work) that could be used when a user is connecting via the handheld browser to know 'who' the user is?

The short answer: Yes

The long answer:

(a) set up a web server
(b) set up a particular page
(c) set up a packet sniffer, such as Ethereal
(d) have the packet sniffer filter http packets coming into the web server
(e) browse the web page using the handheld browser
(f) log the packets that get sniffed and search through them

You should find some http header information indicating things like PIN and service provider, maybe even device model. The packet sniffer will also tell you the IP address the device has (because the incoming packets must have one) but that's transient, depends on the carrier, the time of day, whether the device has gone out of coverage, or changed cell towers, or had its power cycled, etc. You won't see the email address, though. Or any info about the owner. A web browser usually does provide standard information in the HTTP headers - evidence comes from the fact that going to from your BlackBerry shows a different page than going to from your desktop.

Good luck!
