Iphone 4 fits in exactly, all necessary ports are exposed, also speakers and camera are perfectly free. Very good I also like the fact that I have no lock on it - the cap simply goes to and I can to make phone calls simply place the lid on the side that does not interfere. If you fold the cover all around, the phone is slightly slanted and you can play very well or watch videos. In addition, the bag is very sturdy. Nice is also, that if you want to go shopping only once a few things, bills or card is inserted in the sleeve and which do not fall out. And despite the phone shell still fits in your pocket.
