Happy day, iPhoners; your days of living life one hotspot at a time are over. You can now use that data plan for all its worth as more and more apps break through the WiFi-only iron curtain. Last week it was Ustream, the week before Knocking, and now EyeTV has released an updated app able to stream your own personal TV broadcast to your iPhone wherever you are. Assuming, of course, you're not situated within a "coverage gap" -- or a major metropolitan area.
Update: To be clear, this isn't actually a new App Store app, it's a webapp, available at live3g.eyetv.com via Safari and fed by an update to the service's desktop client.
