Utter bull in my opinion.
a) The "phone" would have to have a RISC Microprocessor in it to calculate the velocity etc. Don't exist.
b) A link to another PC would have to be at least at broadband rates...
c) Completing the whole process by 2 spins of the wheel is needed to give time for the punter to place a bet. That's 2 seconds or so.
Possible with a dedicated device that "looks like" a mobile phone though,linked via 433 Mhz short range transceiver to a laptop nearby, maybe....
Such a device would be more use for BlackJack....
