Phoneless in Cyber City

You were walking down the bustling, technocratic streets when it happened... now you must navigate this cyberpunk world with no access to any currency, bio mods, nothing. Conventional projectile weaponry is useless to you, all modes of transportation deny you, all doors have restricted access, even the cities infrastructure can grant you know utility. You have been reduced to nothing but a bumbling Stone Age ape in a society where an individual's value can only be identified by their Persistent Hierarchal Obfuscation Nullification Extrapolator, or phone for short.
