sorry this is a bit off topic, but does anyone know of a way to find out the number if someone withholds it when they phone my phone (a nokia 3210 on one2one), i would be very greatful if anyone could help me.
You could always pick up the phone and ask for their number. =o)
But seriously, I'm not 100% sure about this, but fairly certain that if subscriber A is withholding his number, it is not even passed along as far as the B subscriber's phone. It is passed along in the signalling network along with a flag that "this number is not to be shown", but I don't think it gets passed from the network to the phone at all.
