I really like the space grey a lot too. For some reason white just always looks good to me.
I did see that post about the decals. I thought about order some. I would not mind having the white Apple logo on the back to match the phone.
Last night I took the case off, and tried to push on it to try and get it back into shape, but it did not work. May try the other. May just not worry about it.
Yea the decals are really cool, i got a white carbon fibre one which i would imagine looks pretty smart with a white phone in the case. You could try my suggestion from before but take the phone out first and put a band around to pull the sides in a little and tighten it up. Might try it with mine if it gets any worse, it doesn't bother me at the minute but if it gets any bigger and lot of crap starts collecting then it will annoy the hell out of me,lol
