As far as I understand it, B&O (or LG) has to make something so that it's software from the GX is available on the G1 (it was the case from G9 to GX, the B&O app wasn't available from day 1 on the GX even if it's the same app as on the G9).
So if you manage to buy this combo today, you will have limited functionality until the B&O app appears on the G1 app store.
