Wanna pull the trigger on an iPhone, but...
Will the iPhone SIM be usable on the Treo for DUN, and such? Or, will I be able to activate the iPhone and use my current SIM (64K cingular), or...?

The iPhone SIM is user accessible and does not void your warranty to remove it. You cannot, however, activate you 64k SIM in the iPhone. The iPhone SIM will work in other phones, other SIMs will NOT work in the iPhone.
I have an iPhone and a Treo 680 and do just this.
I use the iPhone for most day to day stuff but swap the SIM back into the Treo for all sorts of business stuff. Haven't tried DUN on the Treo or the iPhone.

I need the Treo as a backup; and one that can perform overseas and DUN, and the like.
One more thing:
http://www.dr-chuck.com/csev-blog/000365.htmlI just swapped my Cingular SIM into the iPhone from the Treo - connected to iTunes - and 10 minutes later I was making iPhone-calls.

what what? Didn't exactly understand.
Can I get it at the AT&T store and activate it there with my Cingular SIM (I'm at work, so could I activate it at work, even though my 'main' computer is at home?)

One thing to note is that even if you swap the iPhone SIM into a phone that supports MMS you still won't be able to send MMS messages. At least I haven't been able to from my Pantech C3b. I havent tried putting my SIM back in my Treo....

I should mention that you could use the iPhone on a non-AT&T sim (such as a Cingular SIM card), you just have to use a 3rd party activation tool. depending on which version of firmware you're using, that could be iNdependence.app for macs or iBrickr for PCs...
