The New Yorker has finally landed on the iPhone.

The app is essentially identical to its iPad counterpart, offering subscribers access to each issue’s content in digital form. The app also offers access to video, audio, and article selections from the New Yorker’s website.

What’s changing, as AllThingsD’s Peter Kafka points out, is that the newer versions of the magazine are much lighter than their iPad counterparts– 23MB compared to an average 100MB. Not only will this make downloading issues far easier; it should also make doing so less taxing on the average data plan.

The app announcement comes on the same day the American Bureau of Circulations (ABC) released its first digital-replica magazine circulation figures, which found that magazine publishers are still moving away from just duplicating print content in their web editions.

Because a simple announcement is not enough in 2012, the New Yorker got Girls wunderkind Lena Dunham and Mad Men star Jon Hamm to do an off-kilter advertisement for the new app, which you can find below.
