I think Jonin is right: ...And don’t you Meamo junkies even dare mention Mappero. I can’t even figure out how to get the thing off Italian, and as a smart phone owner, I shouldn’t have to bother with such nonsense...
-> As you shouldn't bother with such nonsense, then N900 is absolutely not for you :-)

For the one who knows, it is as simple as converting from mp3 to spx ^^
