When the SlingPlayer iPhone app launched last May, it was hamstrung by AT&T's insistence that it stream video only over Wi-Fi. It was an untenable position, given that MLB.com and others already stream over 3G. Today, finally, the carrier relented.
This has been in the works since mid-December, and both companies still need Apple's sign-off before the new 3G SlingPlayer app is available. And don't worry: if you'd previously purchased the $30 Wi-Fi only app, you'll get a free upgrade once the new version is available.
As for what it will do to AT&T's already clogged 3G network, only time and a few dozen dropped calls will tell. [NY Times]
