Verizon has posted specs for any LTE device that will be permitted on its LTE network. IPv6 support is mandated. IPv4 is optional. That’s quite a statement, since IPv4 traffic currently dominates the Internet.
LTE, Long_Term_Evolution , will provide much more bandwidth than current 3G cellular system.
A few relevant quotes from Verizon’s spec:
The device shall support IPv6. The device may support IPv4. IPv6 and IPv4 support shall be per the 3GPP Release 8 Specifications (March 2009)”. (section 18.104.22.168)
The device shall be assigned an IPv6 address whenever it attaches to the LTE network. (section 22.214.171.124)
