    Hi,

    I bought my acer in Holland where I live.
    Thought there was the wwan module included but it was not.. Not happy with that.

    Now I am trying to find a way to install/modify my ferrari so that a wwan/3g module can be installed and used. On my motherboard there is no free pci-express slot.
    At farnell.com I can buy the socket, as well as a sim-card slot. On the motherboard there is a jumper for the sim-card slot.
    If I solder the pci-express and sim card holder in place and change the jumper setting.. should it work?
    I wonder if somebody already managed to modify the ferrari so that wwan module is working.
    On ebay for sale wwan modules, antennas etc.
    I rather don't want to use an usb modem.

    I started the mod.
    Added pci express connector to mainboard and also the sim holder.
    Bought the sierra MC 8780 wwan.

    When I insert the Sierra it is shown in device manager as wireless aircard HSDPA modem. However when I start 3G watcher it says 'no device detected'. sim card is not inserted.
    A few questions.
    1. do I need to insert sim card to get the device detected?

    I also checked the pins on the sierra mc8780.
    Connected are not so many pins.
    9+15 parallel (GND)
    21+27+29+35+37 parallel (GND)
    39+42 parallel ???
    4 GND
    18+26+34+40+50 parallel (GND)
    52 3.3v

    These are the pins of the wwan card which are connected. The rest of the pins are not connected.
    In fact I only have 6 connections.. GND 4 times, +3,3V 1 time and res 1 time.
    How can the signal go to the pc mainboard? is it via 39+41?

    Any suggestions to solve my problem?

    Thanks
