Not that it's really necessary to gin up more enthusiasm for the iPhone 5, but here they go: four television ads for the new phone have hit the airwaves and Apple's YouTube channel. The ads feature a different voiceover actor than previous iPhone spots [update: per CNET, it's Jeff Daniels] and have a somewhat jovial tone; the Panorama highlight ad, "Cheese," is particularly cute.

Got a favorite? Let us know. All four ads are embedded below the poll.
