Apple has certainly relaxed its policy on iPhone apps targeting schoolboy humour, judging by the high number of fart apps appearing on the App Store.
VentureBeat has a piece counting 14 new fart apps released on Wednesday alone. We just checked the UK App Store, and there are now well over 20 of them available.

It's more ammunition for critics who say the App Store is increasingly cluttered by cheap, silly applications. Although given that these apps tend to sit in the Entertainment category, rather than games, it's doubtful whether game publishers will feel too threatened.

However, the fart apps are part of a bigger trend that's seen Apple relaxing its policies on App Store content – the first iPhone fart app, Pull My Finger, was initially refused entry to the App Store.

This trend relates more specifically to games, too, including the release of the first iPhone game rated NC-17, Amateur Surgeon.

It remains to be seen whether this will be followed by other games with adult themes, including drug-dealing sim Underworld.
