It's certainly worth considering what these solutions actually offer. My 
impression is that the phones have some kind of hardware unit for storing keys 
in a similar manner to smartcards [1] - it could well be the SIM that provides 
this, given the relationship between SIM and smartcard technologies - and that 
phones use this mechanism to issue tokens [2].

All of this from a quick tour of Wikipedia based on previous assumptions and 
memories. ;-)
