Why can't I find any custom design cases for Sprints Galaxy S2 D710 but can find a million for AT&t's model?
Check out cell nerds I have ordered from them in the past and have been happy with service and product. I ordered this one in neon green because I was bored of my black otter box. ottter box only comes in black for this phone.
http://www.tridentcase.com Has some nice cases as well but for maximum protection you will end up spending a fortune around 60 dollars or more.
If you are just looking for a pretty case that offers little to no protection of phone I have seen a lot on amazon
Otterbox has two different cases for the SPH-D710. I use the Defender, myself. I got mine through Amazon for a better price than at Otterbox themselves, but that might a Prime discount.
There are also some cases here. I got my wife the blue one.
Thank you for your post. Like the others have stated, there are other avenues to find cases like Amazon, MicroCenter, RadioShack etc. I would suggest searching by Samsung Galaxy S 2 over searching by D710 because most websites do not have the phone listed under the product SKU.
Let me know if you were able to find a case you liked.
