Sound familiar? Ultra-cheap unlimited plans are doing well (in some cases, too well) for everyone that's offering them these days, and it seems that Virgin is no exception to the rule. Following the April 15 launch of its $49.99 unlimited plan, the company announced during its earnings call this week that it's seen a five-times-over boost in unlimited plan adds (yeah, bargain pricing will do that), which dovetails nicely with the MVNO's claim earlier in the year that the crappy economy really set it up for big wins in '09. Notably, the quarter saw income rise 301 percent year-over-year to $19.1 million while operating revenues rose 2 percent to $337.3 million, so things are looking up for these guys just months after financials were looking weak -- so strong, in fact, that they've revised their full year cash flow and earnings upwards. Does this mean we get new Helio gear soon?
