i ordered 3 iPhone 4 by mistake and received all yesterday ( i only needed one) , 2 phones are still sealed and i want to return it for a full refund, there is a return prepaid label included in the box , its a USPS label with strange address on it (SMART RETURN LABEL) and i don't see any insurance on that label either, is it safe to return my phone using that label (what if its lost)? can some one please share their experience return iphone 3g or 3gs in past to AT&T using that smart label and getting their refund. thank you
