Now that the Xperia Play is finally official ahead of a full unveiling at MWC next week, carriers are ready to hop on the bandwagon -- or at least one is: O2 in the UK. Other than a brief tweet, no other details are given at this point, though the quick support of a major European carrier has to be good news for Sony Ericsson considering that device subsidies are no longer a sure thing... and without question, the Play represents something of a Hail Mary for one of the most badly bruised and beaten titans of the wireless industry. Pricing on contract is, of course, a huge open question -- as is North American support -- but hopefully all will be revealed on the 13th.
