Er not quite - what I mean is that if you buy it in the states it will come with Grafitti II installed. As far as I know you can't switch it to Grafitti I. However, if you snag a Euro NX80/73 then users are reporting it still has Grafitti I installed plus you get Bluetooth as well. Just letting you know the options out there.
As Grafitti only allows alpha numeric entry via the Roman system I don't really undersatand the Hebrew question. Do palms sold in Israel come with a different form of input? Or is it like a Japanese palm where you enter words in Roman script and then convert to Hebrew via other add in programs built in to interact with Grafitti?
