It refers o upgrading 5.5 and TM 3.1. I have programmed a couple 5.5s using TM 3.1 and have not had any trouble with phone types (yet). I would start by checking the current patches and SU for TM 3.1 before going to 3.2. I know for a fact 3.2 does not have and will not have have all the fixes reported in TM 3.1 until TM 3.1 SU1 which was not scheduled to come out until late this month.
