I've compiled doc Reader with the Maemo 4.0 SDK (Chinook). This version can be used in N800 (upgraded to OS2008) and N810 (Since I don't have a N810 device, I haven't tested yet. Please inform any issue).

docReader is a graphic utility that lets you read MS Word documents in your 770/N800/N810 or export them to text or PDF format.

The file document conversion is done using 'antiword' utility. If you don't have antiword installed don't forget to get the Maemo port from http://erinye.com/maemo/antiword_0.37-1_armel.deb
