We are all just a few days away from the official launch of iPhone and Apple's marketing efforts are as fierce as ever. There are a lot of reports coming in about big iPhone displays that can be spotted over at the official Apple Stores. Aside from that, there have been also been talks of AT&T updating its own line of stores to accommodate the new mobile phone.

All of these began when people started noticing large, covered rectangular display on different Apple stores. Despite the white cover sheets, it is unmistakable that the displays are actually towering "iPhones". When the covers were lifted, the promotional displays turned out to be video demonstrations for the much-anticipated gadget.

Apple employees at Apple stores still wouldn't give information regarding the phone's rate plans and other details. iPhone is expected to hit retail stores this coming June 29.
