There is no option to change between 2G and 3G in code, the phone hardware makes the decision based on network availability.
If you think about it, if you had this option to force a phone from 3G to 2G that would also force voice traffic onto the 2G network.

Outside of code the only option is to get a SIM card that is not enabled for 3G access that will restrict the phone to whatever network it is enabled for.

Actually on my device you have the choice of 2G only, 3G only, or just let the phone use whichever network has the strongest signal. So presumably there must be something somewhere, although it may be device specific.

You will probably find it is device specific, or is an OS setting, and has a hook into the hardware which would disable one or more parts of the radio hardware that is not available to programmers as it is a phone wide setting.
