Make your number private on the blackberry z10 like the iPhone?

You know like the iPhone you can say caller id on or off

Just call your network and they should be able to arrange it for you

Yes you can, this has been available on All PHONES and you do need to take this with a pinch of salt (6g limit) the consensus is that there were phones before the iPhone, and whilst we're on the topic the IPHONE4 was the FIRST IPHONE to have a camera flash in 2010! (all my phones had a camera flash)
