When mentioning mobile devices and IP, it's important to note that a special protocol is needed to support mobility, and implementing this protocol -- called "Mobile IP" -- is one of the requirements for every IPv6 stack. Thus, if you have IPv6 going, you have support for roaming between different networks, with global notification when you leave one network and enter the other one.
Support for roaming is possible with IPv4 too, but there are a number of hoops that need to be jumped in order to get things working.
With IPv6, there's no need for this, as support for mobility was one of the design requirements for IPv6. Besides support for mobility, security was another requirement for the successor to today's Internet Protocol version. As a result, IPv6 protocol stacks are required to include IPsec. IPsec allows authentication, encryption, and compression of IP traffic.
