Using Pandora in Wifi

[Sdahe]

Hello,

I have Wifi Internet in my house and I use Pandora a lot connected to the Wifi but I wonder... When the iPhone shuts the screen, will it changes to 3G?... I've heard that the iPhone changes to 3G from WiFi when it goes to sleep mode but don't know if it does the same while playing music from Pandora.

Thanks

you should try monitoring your data in the ATT app. look at your data usage in ATT app, then use Pandora for an hour while screen is off and see if anythings changed.
