The next-generation iPhone will likely not only support standard 3G and 4G networks, but also the China Mobile version of 3G, TD-SCDMA, says Sterne Agee analyst Shaw Wu. Based on "supply chain work" by his firm, Wu suggests that the next iPhone will expand on the world phone status of the iPhone 4S by adding both LTE 4G and TD-SCDMA. China Mobile is the only carrier in the world to use TD-SCDMA, something that has so far interfered with iPhone compatibility.
