Well ain't that a kick in the pants. Reports are coming in from newly-minted iPad 3G videophiles that iTunes store previews and Netflix streams are getting downsampled over AT&T's network. The folks at iLounge have been tinkering enough to confirm the iTunes issue (we're still waiting for FedEx to drop off our 3G tablets so we can corroborate ourselves) and, lo and behold, ABC player flat out refuses to work over AT&T's 3G network, instead displaying an oddly familiar message: "Please connect to a Wi-Fi network to use this application. Cellular networks are not supported at this time." Perhaps an update will ensue to fix such limits, but in the meantime, we're sure at least someone at Sling HQ is having an awkward chuckle.
