To make you wait a bit until official announcements of future, here is a video presentation of a possible back cover for iPhone 5. Fact or rumor? It is not known yet, anyway, if this shell is the one that will power future iPhone, many changes can be reported. Indeed, this case would not be back glass (fragile as many have found out), but steel. Moreover, the edges and the back will become one element unlike iPhone 4 and 4S. Finally, it seems that the jack port is at the bottom of the phone (either up as before), and that taking dock is also changing to become much smaller (maybe a micro USB). For more details, I'll let you see this video.
