The SlingPlayer application for iPhone will finally be available tomorrow. Since its January demonstration, there was a lot of discussions as whether or not AT&T (and other carriers) would let this bandwidth intensive app use their networks. thanks to Apple, carriers had it their way and the Slingplayer app will work only with WIFI on iPhone. If you want to use SlingPlayer on 3G, you’ll have to own a Blackberry or pretty much any other smartphone. While AT&T is complaining that SlingPlayer would bring its wireless network to its knees, the carrier has been trying to push its own bandwidth-hog services like AT&T mobile TV. The thing is: it costs $30, per month. Thanks AT&T, but we’ll pass on that offer.
