iPhone 4 Burns itself on an Australian Flight (Update: One burns in Brazil as well)

On the 25th of November this year, an iPhone begin to emit a lot of smoke and glowed red hot shortly after Regional Express (Rex) flight ZL319 landed in Sydney from Lismore. After that “Company Standard Safety Procedures” were followed after which the fire was extinguished successfully. Thankfully, nobody was hurt or injured. The said phone was then handed over to the Australian Transport Safety Bureau (ATSB) for Investigation. Looks like someone decided to go too far with Siri, and she decided to end it once and for all.
Update: We’ve just heard news that an iPhone 4 began to burn after being short circuited. The owner, in Brazil had left the phone to charge overnight, and when he woke up, the phone was smoking heavily and sparks were coming out of it. The authenticity of this news is not as yet verified, but if true Apple could be in a real fix.
