How to clean an iPhone proplery?

I had a case with Lego blocks, and I used to play with it and stick it to the back of my iphone. Now I took the case off there was little circles on the back. Is there anyway to get it off? I've tried just water and a towel and nothing.

Try diluted nail varnish remover but just try a little tiny spot first in case it discolures the case dab it on

  • What is the other space on my iPhone, and how do I clean it up? I just bought a new iPhone 4.It has only 8GB of memory, and a whole 2.4GB of that is taken up by mysterious "other" information. I can't figure out what this stuff actually is or how to get rid of it. I've thought about it being contacts, text messages, etc… But I just barely got the phone. Clearing out the few messages I had didn't make any difference anyway. What can I do to get that cleaned up?
