quake3droid is on the market! Port of Quake 3 demo to Android. You can upgrade it to the full version of Quake 3 by copying your pak0 file over from the PC game's baseq3 folder.
It's really sick, runs great on lots of phones even some low end ones.
Check it out, search quake3droid. Need some feedback and testing!
Controls just like NOVA!
