Don't know much about 3G, but the mobile wallet capability is not new. Korea has certainly had it since my first visit there - I was quite impressed by the way everyone hops on and off busses and trains apparently without paying, and it was explained to me that the fare is automatically paid by the tiny phones which everyone seems to wear around their necks - and universally equipped with the near field technology. No credit cards seem to be involved - the charges all just appear on your phone bill.
