Sprint EVDO IP Ranges?

Does anyone know what IP address ranges Sprint uses for for EVDO?

I run a couple mail servers that I need access to from my Treo. On our firewall, I block everything incoming to them except from a few particular IP ranges that need access. Authentication is required, so its not as if that's the only security measure I'm relying on, I would just prefer to limit the IP ranges that can access it to the only ones that could ever need to.

Currently, I know of:

70.0.0.0 - 70.14.255.255
68.24.0.0 - 68.31.255.255
99.0.0.0 - 99.255.255.255 (I think the actual range is smaller than this, but I didn't know exactly where it ended so I just put in the whole class A).

Today my phone got a 72.x.x.x address for the first time.

I'm wondering if there is a complete or semi-complete list of these ranges somewhere. I'm sure it changes frequently, but it would still be a big help

Thanks
