According to WSOP 2016 rulebook :
- All cell phones and other voice-enabled and “ringing” devices are allowed as long as it does not impede the progress of the game.
[...] but shall not be permitted to text/email any other participant at the table.
- Participants are allowed to use approved electronic devices, iPods, MP3 and other music participants or noise reduction headsets during Live Action play.
[...] cannot be used to collude, cheat, or communicate with another participant during a hand.
PokerNews says that Web Streaming Changes include Live coverage [...] on a 30-minute delay for hold'em and Omaha where hole cards will be displayed
Live streaming of the final table won't make it different as earphones won't be allowed at that time.
Therefore, it seems nearly impossible that players involved in a hand can gather some information from insiders/outsiders.
