Can't establish a connection using a Huawei E176 UMTS modem in Karmic Koala

[Jan Hoffmann]

I can't get a connection using a T-Mobile web'n'walk Stick IV (Huawei E176) in Karmic Koala. The icon of nm-applet just spins around never finishes connecting.

I assume that the problem is related with NetworkManager's transition to modemmanager, since there aren't/weren't any problems in:
 - NetworkManager in Jaunty
 - NetworkManager in Karmic before the update to the version using modemmanager
 - Vodafone Mobile Connect from betavine.net in Karmic

Using Karmic Kola Alpha 4 (fully updated as of 18 Aug 2009)

I am also experiencing this issue with a Vodafone (Huawei E172 & Huawei E220) contract.

No problems experienced in setting up the connection using the Mobile Broadband wizard.
Connection attempted and both green led's light up - Blue swoosh circles indefinitely and no signal steps appear.

I believe that the process is stuck trying to obtain an IP address.

I've added the 'Ubuntu Network Manager' team daily builds for trunk (aka 0.8) which has enabled me to connect using Vodafone 3G contract ( Huawei E172), I haven't tried Huawei E220 yet.

Link for instructions to add daily build can be found at:
