A TEENAGE girl has been burnt after her iPhone allegedly exploded in her pocket.

The eighth-grade student's phone apparently made a big "pop" noise, after which her fellow students noticed smoke coming from the girl's pants.

An email from the school principal Jeff Rodman said the girl was treated immediately by her teacher and classmates before being taken to hospital for "moderate" burns, The York County Coast Star reported.

This isn't the first time a report claimed an Apple device exploded. An iPad allegedly exploded in a Canberra Vodafone store in November last year.

Another report came out of China earlier in 2013, when a woman claimed her iPhone 5 heated up and exploded at the ending of a 40-minute call, sending shrapnel flying from her cracked screen.

News.com.au contacted Apple regarding the incident and are waiting on a response.
