Bought this case day of the 3g launch, have loved it since I first put it on.
polycarbonate case with a rubber finish.
Access to all buttons and inputs
What makes me love the case is the fact its not bulky and it just feels amazing in my hand, the rubber finish really makes it feel more secure in my hands. Also had 2 indents on both sides for a finger, making it again feel better.
Only problem I have with the case is where the mute/silent switch is, once u turn that off, its not easily turned back on, u have to either fit a finger nail between the case on the button, or just kinda rub against it to put it back to on. I rarely put my phone on silent so this isn't a problem I'm constantly dealing with.
Overall I give the case 4/5 would be 5/5 if access to the mute button was easier.
