Any thoughts on this, has anyone tried using IPv6 on the N900 over GPRS?

Requirements:

# Be a T-Mobile USA subscriber with an unlimited data plan

# Have T-Mobile coverage, not roaming or WiFi

# Have a Nokia 5230 Nuron or the Nokia E73 Mode phone. The N900 also works, but it's IPv6 support is much less mature.

# Be willing to help T-Mobile improve the service, forgive us as we grow and refine the service, and accept that this beta service is not supported within any T-Mobile support channel, including Customer Care or any T-Mobile store or reseller. This Google groups forum is the only channel for IPv6 support during the beta friendly user trial.

# Accept that the service is still evolving and that many services like Visual Voice Mail, MyAccount, MMS (picture messages), and several other services do not yet work. Web and Email both work well, but many other data services are still coming online with IPv6.
