I have one of the Ericsson-branded ones of these (MC218), such a great device. It still works too. I had an Ericsson phone (the little flip one) and the little IR modem that plugged into the bottom of the phone. Data was so prohibitively expense I don't think I ever used it.

The phone was possibly a Ericsson T28 (very slim with spring-open flip) or a T10/T18 (quite a bit thicker, with a manual flip).

Even without using data, managing phone book and SMS via the pocket computer was a quite satisfying experience. I used to read and write emails with it, one of the first compact mobile office setups back then...
