You can run most applications, including the Browser. You get the OS 2007 Browser UI but the version of the Opera engine from OS 2006. There are two reasons for this. One reason is that the OS 2007 engine will simply not run. We suspect it is the way it was compiled specifically for the N800 but we don’t have the source code so that’s a guess. The other reason is that the license of Opera that goes with the 770 does not cover the update. Somebody would have to pay more to ship the updated version.
