I had a quick play with the Italian SIM this evening. The APNs don't work due to the framework / telephony not reading the SIM properly (as expected).
I tried a couple of things with proprietary LG files but no luck yet. one thing I tried should have worked (it got rid of the radio logcat errors), but it didn't because of another incompatibility elsewhere... (it killed data for my regular SIM too)
I didn't have a chance to figure out more because my gf stole my netbook from me
If everything goes to plan I should have my desktop up and running tomorrow evening and I can start to research some framework changes.
