no internet with eee pc 901 go - simlock?

I recently bougth the new eee pc 901 go from amazon.
When it arrived, its box had an nasty sticker on it claiming that it
only works with t-mobile.
Some quick googleing brought, that this was most definetly an
software-only problem.
So I wiped the preinstalled Xandros (would have done it anyway) and
installed ubuntu-eee 8.0.4.1.
Everything works fine, except the built in modem.

It is recognised as ttyUSB0 - ttyUSB2.
I built a configuration with pppconfig and tried to fire it on with gcom
and pon:

It seems that the connection is established but terminates immediatly
afterwards.

If I connect an external umts modem using the same procedure (on
ttyUSB3), everything works fine!

Huh? It seems that that the establsihed connection terminates later after
the deflate compression module is registered.

Yes, that seems to be the problem. Unfortunately, I have absolutely no
idea, why this happens.
An external modem (with another SIM) works perfectly...

I found the problem: the module airprime was disabled. After removing
the according file (in /etc/modules) umts works like a charm!

so long
