I have 2 ipod touch 4th gen. Purchased at the same time with the same memory capacity. Im not sure when but at some point i noticed a difference in the Facetime icon on each of the Devices. http://news.cnet.com/i/tim/2010/10/20/FaceTimeIconF_60x60.png While the other device is listed as this http://images.apple.com/asia/education/ipodtouch-iphone/images/onthego_icon_facetime_20101001.jpg I am confused as to why this might be happening. When testing under my own roof with wifi, both devices can send and recieve calls, no problem. But why the different icons and will this possible pose a problem in the future when travaling and using public wifi's?
