All of the documentation I've read shows how to attach one photo. When I try to attach another it just replaces the original with it. Is this possible on the Pre? I've been playing around with it most of the night and haven't figured it out.

Hmmm...I guess I could send an e-mail w/attachments to a text address (ie 1234567890@messaging.sprintpcs.com - or whatever domain the carrier is using).
