I have a Sony Ericcson T616. I don't know if it does the PDA thing, but it does have a calendar and contact list that syncs with iSync. Bluetooth support is pretty good, except for the fact that my contacts' workplaces don't update on sync for some reason.
I would not recommend this phone, however. Its interface sucks; options are strewn about and don't make sense. Waaaaay too many questions pop into the head when you try to dig into the bowels of the phone. The small keys are annoying too.
On the upside, I have an aqua theme installed.
