A "work around" in the EyeTV application for iPhone lets you stream your television from your Mac over the AT&T 3G network, but probably not for long.

Electric Pig reports on this interesting way to get the EyeTV software to allow streaming over 3G: 

"Elgato’s EyeTV app requires you register your Mac to its free My EyeTV service in order to tap into broadcasts outside the house, but use it when your iPhone has only a 3G connection and you’ll see an error pop up, warning that “Live TV playback requires a Wi-Fi network connection.” Tap the OK button, and the app will act as if it can’t receive broadcasts. However, tap the text of the warning message instead, and the Eye TV app will stream live TV over a 3G connection."

But if you want this functionality, you better hurry to download the Elgato EyeTV application from the App Store [iTunes link] because Apple will probably pull it soon after they hear this information.
