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 to take advantage, but we probably wouldn't waste a lunch break giving this a go without a verbal confirmation from your local store manager. Until it's made official, of course.
Update: We've heard from another tipster that the deal is indeed legitimate, and it's for any human with an iPhone 4, not just those who purchased their phone from Best Buy. We'd recommend calling your local store to double check, but things are looking up.
Update 2: Ah, so we've finally received the full skinny from another tipster. The offer only applies to those who purchased their iPhone 4 from Best Buy / Best Buy Mobile or for Best Buy Reward Zone members. Granted, it's pretty easy to sign up for the aforementioned reward program, but those are the stipulations. The official BB name for the product you'll be getting is the Zagg SideShield, which would cost you $9.99 otherwise.
