The iPhone has had an "extraordinary" reception in Asia, "on par with the US some cases," according to analysts Toni Sacconaghi and Sanford Bernstein of Bernstein Research. The pair point to recent IDC data in particular, which indicates that the iPhone now forms 12 percent of all Japanese cellphone sales, not just smartphones. Given momentum and plans to open 20 more Chinese Apple Stores in 2011, it's inevitable that the iPhone will come to more Asian carriers, Sacconaghi argues.
