Any iOS apps for me to talk to people just nearby? I want app for iPhone or iPad, which can search for people within 100 meters (probably need to use Bluetooth), and is able to exchange information with them or talk to them directly. 

Does anyone know of such an app?
Have you tried Bluetooth Chat?


  With this little app you can chat via Bluetooth with other iPhone and iPod Touch (2nd Gen) users nearby.


Customer reviews are good, so it seems to be the solution you seek.
