7650 Bluetooth User ID

Hi there :). Yesterday I was sitting in a pub. My girlfriend went to toilet so I had a little time for my 7650 ;) (*joke*) :). Anyway I'v tried to send a picture, then a small txt message to someone in the same pub...I used bluetooth to find other devices around me. I found two...one were called Nokia 7650, other "Some phone". After that I'm wondering if there is a possibility to change my phone ID. I mean if someone would search for a device using bluetooth and finds me - he would see for example "leez" (instead of Nokia 7650"). Is it possible to do something like that ? Thx for replying.

?
