New Griffin Technology Survivor GB01902 Carrying Case For Iphone Black Polycarbonate Silicon
If you are looking for a tough case all around to protect the IPHONE 4, this is it.  I went through 3 diff type of cases before finding this one.  It will be a little bit bigger than the others + screen touch will be a little bit less sensitive BUT it is worth the trade off (in my mind).  My wife did not like it so she got the other 3 to choose from :)
