Ok, this will sound incredibly stupid, because this is such a simple task. I would like to know how, when I make a call to someone, to block my number, making it appear as private on their phone. Now, I've looked in the "help" section of the phone, and it gives me instructions to click on certain options that don't exist (options --> general options [this part doesn't exist, at least on my phone]). Can someone please help??

okk press the call button to get to call log, then from there press the menu button (left side of the trackball) and go to options, and than general options.

in here you will see an option to restrict your identity.

or
dial *67[number]

and it will work, only on tmobile though......i think

i have cingular and the *67 works on my phone. it shows up as blocked call.

I have had mine set as Mike_187 describes and once in a while it still puts my number through to the person I'm calling.

I don't know how often, but I've had people comment on it. So far it hasn't been a problem, but it could create some real confusion if people returned calls to that number instead of the one I normally give out.

*67 Works on all carriers in the US and works when you use landlines.
