Hi, The proxy of 3G data is bundled with APN and related to carrier's data network configuration. The proxy of wifi is related to wifi network configuration. These proxys has same functionality(Paul had provided a right explanation). However, These proxys can only be used in their "network". That means you can not use the proxy of 3G data in wifi network and vice versa.
Normally, we don't need to set a proxy for WIFI. But bug 870704 introduced a request for this. That's why we add this for WIFI.
