BOFFINS believe that the fireproof qualities of mobile phone Sim cards could make them useful forensic tools.
According to a paper in Forensic Science International, which we get for the spare parts classified adds, Sim card data tells a lot to detectives.
For example, the sim card used to detonate the Madrid bomb helped identify the bombers.
Forensic Science tells the story of electronic engineers Benjamin Jones and Tony Kenyon from University College London who tortured 12 Sim cards using heat, acid, and exposure to James Blunt. They then tried to read the data by attaching tiny probes to the circuit and reading its contents via an interface pad.
It took a lot to knock the cards out. Most could survive Fahrenheit 451 which was nowhere near as good as the book.
This means that any would-be bombers trying to blow something up using a phone have to be aware that they are giving details of themselves to the police the moment the sim card is found. If they know your ring tone they can probably arrest you.

Very interesting if you want to find a group of criminals.
If you check your link you'll find that Farenheit 451 (the temperature at which paper burns) is not mentioned. 450 Celsuis is however.
"They know who called to who with the card. 
In which phones the card has been used and which contacts those other phones have been calling and which cards have been used in those other phones etc. "
