I just received my Reiko Hybrid case that I ordered from Amazon.
I wanted an Otterbox but they aren't making one for the T989. This case seems like good substitute.
It consists of a hard 2 piece inner shell and a soft rubber outer shell. Everything fits together nicely. Feels pretty solid. The screen and camera lens are well protected when laying the phone down. The case has a kickstand that works in portrait or landscape. The external power and volume buttons work great and are easy to push. The headphone and usb jacks have retractable covers that keep dust and dirt from getting in when they are not in use. I like how the hard case covers the edges of the screen protector. No edge bubbling and the pull down notification bar and bottom buttons are not blocked at all.
It's a pretty solid case. I think the phone is well protected from moderate falls. It does add some bulk to the phone but personally I like the heft. For the price, I don't think you'll find a better case for your GS2.
