I find it very odd that while you can write a mail to smsto-800551212@anveo.com the incoming messages are from a random email (that you can reply to) so the messages don't thread. Is it possible to switch this?
Not that I've found, but then again I haven't really looked. I just use the cell providers' email-to-text/mms address after looking it up (I use Data 24-7 for that).
