It's hard to say for certain what exactly this flyer means, but it sure looks as if at least some iPhone 4 owners will be able to snatch a free invisibleSHIELD 4fix (valued at $9.99 or so) from their local Best Buy. Based on a number of tips that we've received, we're getting the impression that the yellow-tagged retailer could be handing out (and installing) completely free side coverings for any iPhone 4 owner that waltzes into a store, presumably as a proactive measure to fend off returns or to upsell consumers on an entire invisibleSHIELD / separate case. Nothing about this notice makes clear that you actually have to buy your iPhone 4 from Best Buy in order
