It looks like Sony Ericsson has filed for the XPERIA Play trademark with the European Union, and the XPERIA Play domain names (.com, .net, and .org) have been registered by the PR agency that handles Sony Ericsson’s European publicity.
The PlayStation Phone is rumored to be launching with Android and will feature a PlayStation gaming experience complete with a slide-out game pad. The device was also recently seen captured on video. Sony Ericsson, which has historically been a Symbian licensee, has also licensed Windows Mobile from Microsoft in the past, and also have launched Android smartphones.
In the early stages of the PlayStation Phone rumors, the device was thought to be launching with Android 3.0, but now it is believed to be launching with Android 2.3 Gingerbread, which was recently launched by Google this month with the debut of the Google Nexus S smartphone.
Pocket-lint is speculating that the PlayStation smartphone from the company will debut in February at Mobile World Congress, a trade event in Europe.
