Sony Ericsson's Xperia Acro and Xperia Arc have been granted PlayStation Certification in Japan — the first devices to receive the certification after their respective launch, and still just the fourth and fifth devices ever to get access to the Android-based PlayStation Suite market after the Xperia Play phone and Sony Tablet S / Tablet P. (The sixth device, PlayStation Vita, is coming to Japan in December.) Both updates are now available over PC connections via NTT Docomo — again, Japan only — with the OTA update rolling out starting today for Arc and next Tuesday for Acro.

No word on certification outside of Japan just yet — Acro is a Japan-only device, but Arc has a European presence and had a limited run in the US as an unlocked GSM device. Of course, now that Sony is taking full control of Sony Ericsson, our hope would be that PlayStation Certification becomes more of a rule than an exception. We've reached out to both companies to see what else we can find.
