Try having that on your conscious assuming you survive that is.
Maybe OT, but has anyone seen the "MythBusters" episode on Discovery about this? They basically do everything they can to short out the phone in a canister full of petrol fumes and it does nothing.
I always turn mine off to comply, but I'm not worried about it, I don't think i'll explode on the forecourt!
