I personally have seen speeds as high as 140Kbps (as measured with
http://dslreports.com/mspeed).  This only happened once, however. :)
Usually, it's more like 70-100Kbps. Latency is rather high, but I'm not sure
exactly what. That page reports 2+ seconds quite often, however i use PuTTY
on my Nokia 7710 with somewhat less latency than that fairly regularly.
Possibly as low as 300ms, probably higher.

It is normally NATed, however if you call up T-Mobile and ask them to switch
you to the corporate VPN service (which, AFAIK, is no additional charge),
they'll tell you to start using the 'internet3.voicestream.com' APN which
assigns you a real, internet-routable IP address. It's not a fixed IP,
however.
