APN+

Currently the APN settings in Android does not allow you to choose IP version for the connection (3GPP lingo PDP/PDN Type). We have a patch for Android which allows you to specify a "Network type" (Choice of IPv4, IPv6 or Dual-stack). This preview done on a Tegra dev board fitted with a kick-ass 21 Mbps IPv6 capable Ericsson Mobile Broadband Module F5521gw shows how it will look like. The connection is IPv6-only combined with DNS64/NAT64.
