I have this same issue on a dell mini 9 with its inbuilt 3G modem. Pretty much the same error.
After updating with the latest PPA i can now connect when in a 3G area, but if the signal is marginal or GPRS it will not connect in Koala.
I can connect with the 9.04 machine but it gives the same error as above when trying it on Koala.
I have updated again last night and will give it a try from a few different locations today.
I also have a E220 HSDPA USB modem, so i will try that as well as the inbuilt modem.
