It isn't clear how much of the proceeds go to the Lance Armstrong Foundation to further cancer awareness and research, but you can still think of this yellow Livestrong hard shell case that Radio Shack is selling for $29.99 as the equivalent of a full-body Livestrong wristband for your HTC EVO.
It's made of "impact-resistant polycarbonate" plastic that snaps onto the back of the EVO like all the other shells you may already be familiar with out there. There are all the necessary cutouts on the case for access to the phone's important bits and pieces, and of course you've got the classic Livestrong branding printed on the back.
I would've liked to see individual cutouts for the flash, camera, and speaker, which looks better to me, but as someone whose family has been deeply affected by cancer, I would still encourage anyone looking for a new case to consider this one.[Radio Shack] Thanks, Carl!
