Can you forward calls?

[Chronicle]

Hi,
I want to get another (probably mobile) phone (for business calls only), but when out i don't want to carry two phones. Is there a way to forward calls from one phone to another, whenever i want?

And if so, is there any way of showing on the other phone that it is a call that has been redirected?

So if i divert a call, i will have to pay for it when it is being diverted?
