The Internet Tablet series, which is what N900 came from, actually was a bit different. Nokia N800 got an update from OS2007 to OS2008, and Nokia 770, while officially supported from OS2005 to OS2006, has been updated via semi-official &quot;Hacker Editions&quot; all the way to OS2008. It was N900&#x27;s Maemo 5 (Fremantle) where they finally stopped supporting earlier models.
