NTT DoCoMo FOMA N900iL: Cellular + Wi-Fi Voice Over IP

This looks like one of the first (if not THE first) WiFi+Cell phones. Snippet available on the DoCoMo phone available at Gizmodo. the sucky part is that (as I understand other articles I have seen) it does not run at WiFi hot spots. Although from a business point of view this might make sense, it makes me as a consumer pretty annoyed.
