HI all I am wondering if I should keep the iphone case I have which is a white incase for my 3gs on or off. I mean I have taken it off today just to remove my clear screen protector, I have now noticed dust and some tiny items around the corner of the screen and the chrome part, which I am now trying to clean out. Whats the best way to clean this phone? I am careful with my iphone, never dropped it on the concrete ground. Only might have dropped it in the car a few times and next to my bed. However it is always in a pocket with no keys or coins. What do you guys think? I was also going to say I do have mobile phone insurance too. So if I ever cracked or damaged it without the case. I am covered that way. So what is everyones opinion?
