Help How to switch between 3G and 2G on Sensation XL

[newsmartphoner]

As there is no forum yet for the XL I am posting here. I need some help, I want to turn off my 3G service while I do not need the internet in order to save money, otherwise keeping the phone connected might endure more costs. I believe there is a way to do it, but how to get to the right place to disable or switch between services?

Thanks.

Nevermind I figured it out already. Anyone looking for the information here is the answer to the question below:

Menu--->Settings-->Wireless and Networks--> Mobile Network (connect to internet)

Unchecking the mobile network box will switch off the 3G service.
