I'm wondering who else besides me it connecting their PDN to a Linux computer (I'm using Ubuntu Lucid). I have a shell script for doing the volume hack, rooting, installing apks (including Google Experience), etc., after the update is done. If there is interest, I'll post my stuff for all to use. I will be updating it as soon as the next firmware release is made available and I have a chance to test it on my PDN. You do need to install the Android SDK (to get adb) to use the script, but that is simple.
