So, I bought the NGP in a clear grey color. When I received the order on the box it came in it said "compatible with iphone 4s". I was a little worried about the fit not being correct around the mute switch, and lo and behold when I put on the case it doesn't fit correctly around the mute switch. I call Incipio up, and state the problem and they let me know that they are working on fixing all the colors to be compatible, but unfortunately right now the only thing they can offer is a refund or a different case. I decided against both options and just cut the case myself. It was relatively easy. I just wanted to give a heads up to all those looking for the case, your particular preference in color may not properly fit the 4s as of yet. On a side note the customer service was great, and the case is amazing. Please don't misinterpret the thread as me bashing incipio.
