Best Buy, one of the largest chain stores in the US, offers free to all iPhone 4 owners an InvisibleSHILED 4Fix kit from Zagg. It is about the kit presented by me here, that is, a set of foils that stick over the phone's antennas to prevent direct contact with them, and implicitly prevent signal loss. This InvisibleSHIELD 4Fix kit costs $10 at Zagg or can be purchased together with the InvisibleSHIELD kit for $24, which is the normal price of an InvisibleSHIELD kit. It seems that Best Buy offers and installs this kit completely free of charge to all iPhone 4 owners, regardless of whether they purchased their terminal from Best Buy or not.
Best Buy made an interesting move, they will win a lot in terms of image, and Zagg will probably sell a lot of iPhone 4 kits.
