[UPDATE] VERY IMPORTANT: The solution I posted below is a bit hackerish and has been refuted by Rui Carmo who makes available a great resource for Acer One owners that want to hack their system a bit without breaking down functionality. For your own sanity, please take a look at his notes.

Today someone asked me if I could try to get the Huawei E220 to run over an Acer One. I agreed. Boy was it hard..

First of all, some background info. Do not skip it

1. Acer One brings its own Linux flavor, some distro based on Fedora 8 (Werewolf);
2. This distro bundles XFCE window manager;
3. There’s one OSS tool from Vodafone R&D Labs available here (actually this is the tool I use for my connection, even that I’ve a contract with other operator, Kanguru);
4. Download vodafone-mobile-connect-card-driver-for-linux-2.0.beta2-fedora-installer.run as that was the one I tried successfully;
5. Be sure to be running the latest version of software on your install;

Got it? OK, let’s go to the terminal. If you don’t know where you can find it, you should quit reading this post. Now:

1. sudo -s
2. yum remove linpus-lsb
3. yum install redhat-lsb python-twisted pyserial pytz gnome-python2-libegg
4. ./vodafone-mobile-connect-card-driver-for-linux-2.0.beta2-fedora-installer.run
5. If everything goes right, a dialog will appear asking for you to insert a space-separated list of users who will be able to use this software. Simply put user

This should do the trick. Now just run sudo vodafone-mobile-connect-card-driver-for-linux and it should ask you to edit info regarding your connection. To the Vodafone Portugal clients it should appear a dialog which asks you if you want to load Vodafone Portugal configuration.

Neat!

Any doubts, just comment!
