If you are in the Buenos Aires subway, this is the number you dial if you have an emergency:
Good thing they limited it to 5 figures and phones don't let you use punctuation. I really, really, really would like to know why they decided to use this number. It's not easy to type, it's not particularly easy to remember, it's not used for emergencies anywhere else, as far as I know. Is it a case of a math nerd with power?
BTW: this is the first time I buy a cellphone with a camera. It also happens to have bluetooth, and it works flawlessly with Linux.
