Well I can't really do that because I have to hold it VERY close to the subject. Would moving the lens farther away from the lens of my camera allow me to shoot subjects farther away, or is it the other way around?

I do have much better setup, a DSLR camera and a 180mm macro lens, but once in a while my DSLR is not ready, I only need to the pull out my phone and a "macro lens" from my pocket, and take some macro pictures.
just found the answer on these cell phone attached lenses, and there are more available in full range: fish eye, wide angle, long range, macro... lenses!
