Both 3G modem and Wifi?

I need to be able to connect to a wifi network and send stuff over the 3g modem, is that possible?

I'm creating a little program that acts as a portforwarder between the client > internet > phone > wifi > "hardwar开发者_高级运维e connected to phone using Wifi"

This is not supported through the Android SDK, sorry.
