Well it really has a fast and reliable connection, but only if people 
will stop using
it with PPP and do a cdc-ether bringup instead and run usb/ethernet 
connection directly
to the module. ;-)

But ok, that can't happen until next week or so when we've been able to 
publish

So, I strongly suggest to hold off playing with PPP and instead wait for 
some
shiny glittering features coming out soon...
