Another case I would recommend the diztronic case. It's currently on preorder. I've had one on my last three phones and though it's a boring matte black, it feels great in hand and is very minimal. It's got a nice grip to it and isn't sticky or slippery. Normally their cases are available with prime so you may want to wait until release to find out if amazon will have them in stock for prime
