When you turn Wi-Fi on with a 3G enabled iphone, does your phone stop using 3G?

When youre in a Wi-Fi hot spot and you switch the Wi-Fi switch on, does the 3G stop being used or does it continue to go down even while the Wi-Fi is on? Should I switch the 3G switch off when Wi-Fi is on to conserve data?

When your Wi-Fi is on your phone quits using 3g unless you are receiving a picture message from someone.

When you have Wi-Fi and 3G on at the same time, and you are getting Wi-Fi connection, you 3g will automatically be disabled until you no longer get your Wi-Fi connection. However if you are using Wi-Fi and you turn on your hot spot, meaning you are now providing Wi-Fi for another device, your 3g will be enabled even if you were connected to Wi-Fi earlier on. Hot spot drains your battery so turn it off once you are done. But you can always leave your Wi-Fi and 3g on. Hopes this helps!

Yes. Wi-Fi takes president.
