According to the latest numbers by GfK Japan (via Analytica1st), the iPhone has become Japan’s best selling mobile phone. The numbers refer to the week October 18-24 and are the result of a survey across 4,000 point of sales.
As you can see, the iPhone, both in the 16GB and 32gB edition, is the only Softbank device in the chart, which includes cellphones by NTT DoCoMo and KDDI au. The iPhone 4 came out in Japan on June 24th, but Apple –as usual – hasn’t released country-specific numbers of units sold.
