Earlier design concepts updated
New photos depicting a front digitizer and display assembly for an alleged next-gen iPhone show similarities to the iPhone 3GS, according to RepairLabs. Specifically the site says that the new phone "looks like it has a plastic 3GS-type midframe running around the digitizer and glass LCD assembly," and has a "striking similarity to a 3GS, with the bottom screws and brackets."
RepairLabs adds that based on the width of the bracket, it believes the charger port will have to be smaller. Apple is widely reported to be switching to a new dock connector format with the next iPhone, ditching the 30-pin format it has used for mobile devices since early into the iPod era. Other devices will also presumably make the switch, possibly including a new "mini" iPad.
"These pictures suggest that the LCD may pull apart from the Digitizer, given the rivets on the sides. (This is similar again to the 3GS, but a departure from the 4 and 4S.)," RepairLabs also notes.
