Generally speaking, cell phones don't have EUI64 identifiers and the network allocates a (typically random) interface identifier part that the phones can use when they generate their addresses. Furthermore, the phones get a new prefix part every time they reconnect to the network, e.g., after being out of coverage for a while. And on top of this, you can also use RFC 3041... I'd say we are pretty well covered for privacy. When a laptop-phone configuration is used, the laptop's EUI64 may become visible more easily. The changing network prefix and RFC 3041 can help there.
