and the 650:

We all know that Pro and the 650 has SMS issues. Many have said that you CAN'T delete the mail portion whilst some say you can.

Well you can. Just make sure that you change SMS to None under Agendus Preferences. It will change it back to messaging on its own, but it somehow forces Agendus to find the proper messaging utility.

I'm going to monitor over the next few days before I decide whether to get rid of Agendus.
