yes.
buy a fisheye-lense -.-
there is a rather popular product that does the job quite well, just look for "fish eye iphone" on amazon. it comes with a magnetic ring that you have to glue around the cameras objective, and the fisheye-lense that sticks to the magnetic ring. work on all phones that have a plane, straight back surface (i have a nexus s and i assume i cant glue the ring on it because its camera is sticking out a bit and has a slanted transition to the back cover.
