Well, it looks like the struggling Helio may not be falling under the Virgin Mobile umbrella quite just yet, with the MVNO's parent company, SK Telecom, now calling such speculation ""groundless." An SK Telecom spokesperson further added that it was not in "any sort of talks" with Virgin and that it remains "committed" to Helio, although the company did seemingly leave the door open somewhat by saying it is "actively seeking opportunities" to expand its service in the U.S. Muddling the situation a bit further, Reuters reported on Friday that the two companies were in fact in "early talks" about a deal, although the source behind that story was apparently unable to confirm whether the deal was actually a merger or a purchase, or one of a number of "other possibilities."
