Great.  I actually just bought a T-Mobile Rocket 2 as well, and I'll do
some more testing and then commit to a permanent solution.  I do not
recall what the situation was when I implemented this support over a
year ago, because I had to mail the device back to the owner right after
I got done.  But at the time, I don't believe the AT%IPDPADDR command
returned different results, and did *not* include the netmask
information.  That  meant static IP addressing with a /32 prefix, which
is currently hardcoded in NetworkManager because every Icera-based and
Option HSO device that used static addressing also used a /32 at that
time.

I see now that the Rocket 2 had a firmware update in March 2011, which
was 2 months after I returned the modem to its owner, so perhaps that
firmware update adds the DHCP support and extended AT%IPDPADDR command
information.

Based on your results, the device needs either:

1) DHCP, but we can't autodetect whether it's capable of DHCP or not,
hence the udev rules

2) static IP, but with the extended IPDPADDR info parsed, and possibly
using a non-/32 prefix
