I got a Silicon Case from chillicase.co.nz which is nice looking but its just too soft and the iPhone slips out of it all the time :-( Putting it in my pocket half the time when I take it out the phone has slipped out of the case.
Also as the iPhone 4 and the iPhone 4S side buttons are slightly different and they don't line up properly (making the vibrate switch a little hard to use (but the volume buttons seem to work fine))
Maybe a slightly harder rubber case but I don't want to spend $30-$40 each time to try a case just not to like it.
I've checked and no one in NZ has iPhone 4S cases as far as I can tell . I'm looking for something which looks nice AND protects all the sides and corners. The biggest problem with phones is the dropping of it and the thin nice looking cases seem to give no protection at all for dropping them on the corners.
