Android is catching up to the iPhone in Japan but is much further back, new data from comScore found on Thursday. Google's platform exploded over the last half of 2010 and jumped from just 435,000 users in June to almost 2.2 million at the end of that year. The gap with Apple was noticeably wider than it was in the US, however, as Apple still grew from about 2.6 million Japanese owners just at the cusp of the iPhone 4 launch to 3.8 million six months later.
