After days of downplaying speculation about a merger of sorts, Virgin Mobile USA has put out a statement saying that it is having preliminary talks with SK Telecom about "strategic opportunities" concerning Helio, the MVNO SK Telecom owns in partnership with EarthLink.

Reuters reports that SKT, the leading Korean mobile operator, isn't saying whether it's considering buying Virgin Mobile USA's business or attempting to sell Helio.

Here's the full text of Virgin's statement, issued this morning:

Virgin Mobile USA, Inc. confirmed today that the Company is in preliminary discussions with SK Telecom to explore possible strategic opportunities. Virgin Mobile USA said these discussions are in early stages, and there are no assurances that any transaction will result. Virgin Mobile USA will have no further comment unless a definitive agreement is reached.
