Seidio Innocase and holster
It's hard to find a good case for a slide phone, mostare junk and break within a week. I bought this on Amazon for less than $5, it was an open package return. (you probably won't find it for this price) But it is definitely worth so much more.. I tried everything else including Otterbox and this is the longest lasting case I've had. And the holster is even better, it is made for a phone in a case and the spring clip is awesome I haven't had the phone come out of it yet. If your having problems finding a good case and holster I recommend both of these, you can find them together and separate. I am pretty sure there is a holster that is made for the Shift without the case too. My case is starting to wear down now (too many battery pulls maybe) but it has still lasted 3 times longer than the Otterbox.
