Hmm. I should say that the N900 is the first Nokia phone I've owned (and, admittedly, given the way Nokia is headed, it may be my last). Looking at the specs of the 3110c, the current Pierogi design may be a little on the heavy side for it. But I don't think it would necessarily be impossible to do. Even converting it to Java could be done, although I'm using a few C++ tricks right now that might not be available in Java.

If you're interested, the Pierogi source code is available, if you want to try porting it.
