It's been just over a month since we broke the news that Sony's working on an Android 3.0-based gaming phone with PlayStation branding, and a new job posting seems to indicate that progress is being made -- the PlayStation division is looking for a senior server engineer in London with "experience in mobile development, specifically Android." The rest of the listing sounds like this person will be involved in running an online game service, which certainly makes sense; Sony would do well to counter Xbox Live on Windows Phone 7 and Apple's Game Center with PSN on their own device. Either that, or this just means nothing -- but you know us, we're eternal optimists.
