Whereas AT&T's move to tiered smartphone data pricing signaled "the end of unlimited" to some, Sprint subsidiary Virgin Mobile USA has just defied that notion with an all-you-can-eat broadband buffet priced at $40 per month. First reported by IntoMobile and confirmed today on the carrier's Facebook page, the plan will replace existing $20, $40 and $60 monthly offerings that currently top out at just 5GB, so only those accustomed to paying $20 a month (for 300MB) won't get a totally sweet deal. As you can see above, the $10 for 100MB over 10 days plan will still stay pat, so you can still choose whether to sip or gulp down Sprint network packets when the plans purportedly go into effect on August 24th.
Update: Virgin Mobile's PR department just let us know that there's been a slight delay with that spiffy new unlimited plan, namely that the company's website hasn't been updated to allow you to purchase the new service quite yet. They're telling us the offer should be up within the next 24 to 48 hours, and appear in retail stores in the weeks after that.
