It's probably easier to watch the World Cup on your phone or tablet than you think
Most of the time, watching big sports events live online is a pain. Typicallly it involves paying for a subscription or messing with illicit live streams that (rightly) give you the heebie-jeebies. I figured it would be the same way for the World Cup — and as a casual fan at most, there was pretty much no way I was paying for the privilege or dealing with the headache.
But it's really amazingly easy, and pretty much free.
I say "pretty much" because you do need to have a cable subscription that includes ESPN, and it's safe to assume you're paying for that. But if you do, and your cable network is supported by ESPN's WatchESPN app, you'll be able to watch every single World Cup match on your Apple iPhone, iPod touch or iPad (running iOS 4.0 or later) or Android Mobile or tablet device, including the Kindle Fire (running Android 2.3.3 or later) without paying an additional cent. Download the app, sign in using an account you create with your TV provider, and you're all set. On a laptop or desktop PC, go to watchespn.com, and you'll be able to see matches from there, too.
Want to listen in the car, or at your desk? Any gizmo that lets you stream ESPNRadio will give you what you need — and since ESPNRadio streaming was just added to iTunes Radio, if you have an iPhone you don't even need to download an app. Look for it among the stations at the top of the iTunes Radio section of the Music app (or search for "ESPN" if you're having trouble finding it), and tap to listen.
