In honor of Major League Baseball's opening day (today! Go Giants!), Volvo has unlocked the paywall on streaming live games onto all iOS devices. For the entire month of April, all streaming MLB games will be free to view on MLB.tv.
Of course, to view the streaming content you'll have to be subjected to some Volvo ads, but for baseball fans it seems a small price to pay. It also guarantees a lot of eyes on your ads, which is something that may become more popular as more and more high-profile paywalls are announced.
Sadly, it's not completely free — to access the streaming content you need to pony up for the official MLB At Bat iPhone or iPad app, which is $15. Android users can get in on the action, too — you'll be able to watch one free app per day.
