mine has no issue but that would definately fall into the catagory of factory defect... calling and having them replace it should be a no questions asked. they have devices to replace it with from day one... if your close to a store, with the right attitude up front and a smile on your face, i would say they will have no issues, if after the date of return (14 days ) i would not even bother with the store and call it in to 611... and expect your new phone delivered within a few days... luck with that mate and ...
Though my wife too would roll her eyes and taunt me, she would be the one sighning for my new phone at work a few days later... (HAHAHA, under my breath of course )
Mine was pretty loose too. Some silicone cement smeared around the volume rocker as well as the power button (and then wiped clean) fixed it right up.
I was at a local Best Buy and Verizon store yesterday for various reasons, and every model there (2 at Best Buy and 3 floor models at VZW) had pretty loose volume rockers.
