This is not true at all. And forgive me if I take a small bit of offense to your assertion. Maemo Mapper was first developed on the 770, it has always worked on the 770, and it will always work on the 770. You just joined in November, so maybe you weren't around when the N800 was first announced, but I was perhaps one of the most vocal developers against the way Nokia abandoned the Nokia 770 and OS2006. Making OS2007 work on the 770 should have been a priority. I still don't agree with the way Nokia handled it, but what's done is done. The only thing I could do was vow to continue support for the 770 (because, hey, I own one, too, and I'd like to use my own software on it). And trust me, Nokia didn't make that particularly easy. They did the same thing with OS2008 (breaking backward compatibility), but at least they learned from their mistakes and made OS2008 available for the N800. OS2008 brought hardship only to developers, leaving users insulated from many of the negative effects, although applications generally still need to be ported to OS2008 before they can work. Every single release of Maemo Mapper includes a version for the 770, with the exact same capabilities as the other versions. Just look at the release list in the Garage. OS2007/N800 support started with v1.4, and OS2008 support started with v2.2. The most recent version, v2.3.1, still supports OS2006 and the Nokia 770. And all future versions will run on it, too. As for OS2007HE, Maemo Mapper can work with it, if you're willing to do a little more work (and if you're using the "hacker edition" firmware, then you're obviously willing). Personally, I don't use OS2007HE (so I can't test Maemo Mapper on it), because its benefits aren't worth putting up with its shortcomings, but some people do, and some people run Maemo Mapper on it. Or maybe you're talking about Maemo Mapper abandoning OS2005? It is true that Maemo Mapper v1.0 and greater do not support OS2005, but that is because there is no reason to run OS2005 on the Nokia 770. In fact, I would be surprised to hear that even a single Nokia 770 is still running OS2005. Users stubborn enough to run OS2005 probably don't have a problem sticking with Maemo Mapper v0.2.4. Anyway, sorry for the rant, but I've spent a lot of my spare time making sure that Maemo Mapper works on every version of Maemo that is available. And I will continue to spend time with that goal in mind, at least as long as I have working 770 with which to test.
