How can I mirror one iPhone 4 to another? I have heard you can mirror an iPhone 4 so that whatever happens on one phone you will see on the mirrored phone. Can this really be done and if so how do I go about setting up the two phones? I am very technologicaly challenged, but I'd like to monitor my daughter's iPhone.
Without jailbreak, No.

With jailbreak, still, No.

Furthermore, it is considered pretty rude to do that IF it's for spying on someone.
