Just got my Mez a few days ago - first smartphone - YEA! It is running Froyo. I understand that long messages will be changed to MMS, but while I am typing a message (long OR short) I get popup notification that it is switching to MMS then a few words later it will switch back to SMS. Is this something I push in error while typing ( I make a lot of errors!)? Has anyone noticed this (the switching, not my errors)?
