I got a nice case with kickstand and a holster.
Gives me the grip I need, because the phone is slick enough, I have trouble holding on to it with one hand otherwise, especially when my 2 year old is squirming around in my lap.
Mine is black on black, but it comes in other colors. Bought it for $3.75. It has a $2.99 shipping, but I found a coupon and got free shipping, so got it delivered for $3.75. Well worth it. Same case from other buyers were as high as $13.98. What can I say... I like a bargain.
EDIT: A little additional info for anyone shopping for something like this. This one is better made than the one I used to have for my 520. It has actual metal pin hinges for the kickstand. The one I had for the 520 had plastic pegs that slid in the rail, and one had broken after a couple months of use. This one uses the kind of metal pins you find attaching leather watch bands to the watch. Very well made, this case. Much better made than the price suggests.
Also, sliding in and out of the holster is quite easy and can be done with two fingers, yet it doesn't slide out accidentally. It holds quite firm, but doesn't get stuck, and slides out well.
