Image Management

I've recently received a Sierra Wireless MC8355 based on the Qualcomm Gobi
3000 and as
I understand, (or perhaps misunderstand) these devices can operate across a
variety of
cellular networks by selecting the appropriate firmware to load on the
device. (i.e. there are
AT&T, Verizon, T-Mobile, ..., firmware variants an end-user can select
from.)

I have successfully used libqmi to list firmware image on my device (see
below), but I have not yet found
any method to upload/download firmware images to/from my device. Can anyone
offer some
advice in this area?

[/dev/cdc-wdm0] Device list of stored images retrieved:

    [0] Type:    'modem'
        Maximum: '6'

        >>>>>>>>>> [CURRENT] <<<<<<<<<<
        [modem0]
        Unique ID: '00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00'
        Build ID:      'D3200-STSUXN-1577'
        Storage index: '0'
        Failure count: '0'

Also in this vain, I have spent some time using Code Aurora's Gobi 300 API
but it has been
very slow going as the code is quite 'dense' and its documentation nearly
non-existent.
