Since the Calypso chipset is 2G a "3G SIM" will only work if it contains
both the USIM and SIM applications.
I would expect that this is the case for most operators that have both
2G and 3G networks.
It is less likely that operators such as 3 would put a SIM application
on their cards - at least I can't think why they would - since this
would only be used by a 2G handset which couldn't use their network.
