How can I restrict iPhone inbound and outbound wifi traffic?

[A-Dub]

Long story short, my brother is getting married and we're webcasting the wedding on Livestream from my iPhone. To prevent an accidental Facebook notification, email "ding", etc during the ceremony, I want to restrict the wifi traffic on my phone to only the Livestream for Producers app.

Does anyone know if there is a way to do this? My phone is jail broken, so if there's a Cydia app then I can use that.

Thanks!

And how are you going to prevent receipt of email, text, phone calls, whatever over cellular?

Following Neil's lead, I suggest disabling notifications from all other applications, along with logging out from the Facebook app. In the case of Facebook, you should also disable notifications from within Facebook since it's possible to set up notifications via the app, email, and SMS. Also check for other applications that push noticifications (examples are Twitter and Foursquare).
