Postscript: after I had the shell all day today on my iPhone, I regret to say that the envelope in his pocket at least one corner repeatedly triggers the phone. This can of course easily get protection between shell and iPhone.
Hard Case:
the hard case, I now can also test! It sits so precisely on iPhone, looks very classy (many acquaintances have said) and makes the iPhone a bit grippy. There are no problems with your pocket! I think the case is for the price a Gift! I'll see that I still order two pieces. Something better, I have not found so far!
Addendum: I have the hard case now for a few weeks in operation. Still fits like a glove! No wiggle, very good grip! But unfortunately it scratched very quickly! I think it would be a little nicer if there is something "milky" would! Then scratch, would stand out not as fast. This clear case one already sees the scratches significantly.
