F12: Mobile broadband dongle problem

[Michael McConnell]

Hi,

I have a Huawei E220 mobile broadband dongle on 3UK. In Fedora 10 this 
worked beautifully.  However, having upgraded to F12, I get the 
following in the log when I try to connect:

Nov 22 10:45:57 Sonozaki NetworkManager: <info>  Activation (ttyUSB0) 
starting connection '3 Internet'

However, I can point Minicom at /dev/ttyUSB0 and I can get the expected 
results by throwing AT commands at the unit, e.g:
ATI
Manufacturer: huawei
Model: E220
Revision: 11.117.09.04.00
IMEI: [hidden]
+GCAP: +CGSM,+DS,+ES

OK

(I hid the IMEI.)

Any suggestions (short of going the old-fashioned route and writing my 
own dial-scripts)?
