My experience is that it doesn't uninstall properly, there is a dependency problem somewhere. Check that the packages 'wicd' and 'wicd-daemon' are both not installed and that you have rebooted. 

Here are the networkmanager packages I have installed:

bob at hoss:~$ apt-cache policy network-manager-kde
network-manager-kde:
  Installed: 1:0.9~svn1112085-0ubuntu4
  Candidate: 1:0.9~svn1112085-0ubuntu4
  Version table:
 *** 1:0.9~svn1112085-0ubuntu4 0
        500 http://gb.archive.ubuntu.com/ubuntu/ lucid/main Packages
        100 /var/lib/dpkg/status

bob at hoss:~$ apt-cache policy network-manager
network-manager:
  Installed: 0.8-0ubuntu3
  Candidate: 0.8-0ubuntu3
  Version table:
 *** 0.8-0ubuntu3 0

My USB HSPA modem also uses the 'option' driver, so yours ought to work with networkmanager. I also have no trouble with WiFi networks.

Some people, myself included, have found that Knetworkmanager works a lot better if KWallet is disabled. You can do this from System settings.

If you're determined to use wicd for WiFi networks, then your only other option for mobile broadband is KPPP. You would need to know the exact sequence of AT commands to send to your modem to make it work. I'm afraid I can't help you with that.
