So I purchased an Incase Slider at the Apple Store about a week or so ago. Since putting it on my phone (3GS) it's started to groan and creek near where the two pieces meet together, and it generally just feels flimsy in that area. If you apply pressure to either side I can make it flex and creak. Doesn't feel like a rock like my buddies does. I bought it at the Apple Store, and I chunked the packaging and stuff it came in. If I go back into the Apple Store can they swap it out for another even though I don't have the packaging? I assume they have my receipt there on file.
