Recently, I've managed to connect my T30 thinkpad laptop running Ubuntu 8.04.2
to Movistar (Spain) 3,5G Network.  It was tricky, and success only by 
using combination of comgt [1], usb_modeswitch [2] and wvdial [3]. 
Since I don't really like GUI based things, I didn't bother much here 
for GUI and did the connection on the command line only.  
Assuming that you have already installed necessary software 
or modules [1,2,3], by the below description you maybe able to
do the connection.

Inserting your sim-card properly to Movistar's usb dongle is the first
important step. Afterwards, the following command set will connect
you to the Internet if your config files are setted properly (see below):

# killall -9 nm-applet
# modprobe -r serialusb
# umount /media/movistar
# usb_modeswitch
# modprobe usbserial vendor=0x19d2 product=0x0066
# comgt -d /dev/ttyUSB1 -vvv
# wvdial movistar

Before wvdial, you may want to run wvdialconf command to generate
your /etc/wvdial.conf. Alternatively you can edit manually as follows:

-- cut from here ---

[Dialer reset]
Modem = /dev/ttyUSB3
Init1 = AT

[Dialer movistar]
Init2 = ATZ
Init3 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init5 = AT+CGDCONT=1,"IP","movistar.es";
Modem Type = USB Modem
ISDN = 0
Phone = *99***1#
Modem = /dev/ttyUSB3
Baud = 9600

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Stupid Mode = 1
Modem Type = Analog Modem
ISDN = 0
Phone = *99***1#
Modem = /dev/ttyUSB3
Username = MOVISTAR
Dial Command = ATDT
Password = MOVISTAR
Baud = 9600

-- to here ---

The vendor and product numbers seen in the modprobe command above 
can be obtained for your modem by

# lsusb  -v

See the active one and check out vendor and product information. Another
important/tricky points are 1) providing your pin number during comgt 
command 3) sometimes modem USB device isn't ttyUSB1 but ttyUSB3 in the 
/etc/wvdial.conf file, even it is reported/identified as ttyUSB1 by 
modprobe.
