Binary package hint: network-manager

I've got a Huawei E169 (seen as E620 by lsusb). Until Jaunty it used to
work. I'm not sure about Karmic.

Now in Lucid it works only where there's UMTS/3G signal, but fails to connect in areas with only GPRS/GSM signal.
I've tried the same SIM card with another dongle and it works with GPRS too, and the same dongle+same SIM card in a UMTS area and it works. Same dongle, same SIM card, same GPRS place (my home), different OS (Windows 7) and it works (just to make sure I do have GPRS here and that the problem is not faulty hardware). 

Maybe this is a duplicate of bug #446146 but I'm not sure.
