Ok so I have gone through about 8 different cases, and have seen 3 different versions. Well today for the hell of it I went to BB to see if LF has sent out a need model, and low and behold another version. The last one I got that has the foam on the back side below the apple logo. This one did fix the speaker vibration and the issues with people hearing there echo on speaker. Sometimes I would get the proximity sensor issue but not a lot, also the pill owing affect due to the foam at the top of the front. Well the one I picked up today is a little different, where the foam below the apple logo it has 2 plastic pieces, where the foam was white is now black and seems a little skinner. On the front there is no longer the foam piece at the top, there little foam pieces inside corners and sides, also the plastic on the home button is skinner. I will link the pictures. I currently am doing the water test and will give some feed back once I try out this version of the case.
