When Sony divorced Ericsson from their joint venture early in the year, they paid over $1.3 billion to the Swedish mobile magnate in order to regain full control of the company and shed its European name from the family tree. We then witnessed the birth of Sony Mobile. The only logical thing to do next is for Sony to pack its bags and move out of the old continent.

After a relatively short stint in Lund of Sweden, Sony announced today that it will be moving its mobile business HQ to Tokyo, Japan. The company said that the move is pursued so that it can better integrate the mobile arm with other business units in its home country. Ultimately, it’s a vital decision to make if it were to compete better with the likes of Samsung and HTC.

Sony Mobile President and CEO Kunimasa Suzuki said the move focuses on efficiency. “A more focused and efficient operational structure will help to reduce Sony Mobile’s costs, enhance time to market efficiency and bring the business back to a place of strength,” he said in a statement.

As part of the restructuring, Sony also revealed that it plans to cut about 1,000 jobs from the soon-to-be defunct mobile phone plant in Lund. The layoff is expected to be completed in two fiscal years or by March 2014. We hope Sony will not find itself in hot water like what Google and Motorola faced earlier.

There are plenty of reasons to be optimistic about Sony’s Android future. From the recent AOSP experiment on Xperia S, the introduction of the next generation Exmor RS lenses, to future Xperia phones that may ship in early 2013 for under $200 – the move should allow Sony to get back on track with the innovation process and stop simply playing catch-up with other Android phone makers.
