How android application work with 3G/GPRS/EDGE

Question

I developed an android app to receive a location and then send a message to collect at a MySQL server via XMPP protocol.

I want to know a differences between using WiFi and 3G/GPRS/EDGE.

If I use WiFi, it can connect to server directly, right? But if I use 3G/GPRS/EDGE, is it possible to send msg to server? If possible, am I set up or need to do something to check the differences mobile connection?

Consider setting up an HTTP service that would pass parameters to the database and pass the records (if any) back. This way it will work over public networks for sure.
