It may help to let the techs know what type of connection you are using, WiFi or 3G and whether there is any difference between the two connections types.
You might also keep in mind that your workstation has a much faster processor than your mobile device so a lot of things will be slower on it.
I am hooked up with a WiFi connection. Have not figured out how the 3G connection is set up. Most of my work will be done within the WIFI range.
