I bought this to use with my Iphone 4s using the attachable keyboard cause it made the phone thicker.  When I discovered I did not want to use the keyboard, I still found this case very useful.  I have a silicon cover on my phone to protect it and that makes it not fit well in the cases designed for the Iphone 4.  If you use a protective case on your Iphone, this pouch is the way to go! Some cases just have the belt clip, this one has the hoops too!  I use them if I am doing something very active and do not want the pouch to bounce off my belt.  I recently upgraded to the Iphone 5 and put a silicon case on it too...it fits perfectly in this pouch.  I like it so much and mine is getting beat up enough...I think I will order another one right now!
