Virgin Mobile's October IPO raked in a solid $412.5 million -- a little bit off its highest estimate, yeah, but still boatloads (and when we say "boatloads," we mean "hundreds of millions of dollars") higher than what it had thought it could get when it first announced its intentions to go public. A new class action suit alleges that the $412.5M figure was inflated, though, by Virgin's fudging of third quarter revenue figures which conveniently have since been revised down to indicate a $7.3M loss. Unfortunate coincidence? Maybe, but Virgin's stock fell a solid 14.4 percent on news of the redone numbers, so we can understand that a few shareholders might be grumbling about the sitch. Meanwhile, the MVNO's form letter reaction to the news is in full effect, claiming that the lawsuit is "completely without merit," so we're guessing this one's gonna be tied up in the legal system for a hot minute or two.
