Transfer calls, two iPhone 4, both phones ringing I have two iPhone 4 and I'd like to transfer calls from one to the other. Moveover I'd like to ring on both phones. Is this possible? I know how to transfer calls, but only one phone rings.

Thank you for your help.
The First point is,your carier is providing you the facility  your asking,
if yes then you will get it in the call diversion option.
