Can I use my phone to connect with the internet through wifi instead of 3g? I have a wifi connection option. Will I still use up MB? I didn't sign up for a data plan on this phone and I don't want to pay for data. It is a line for my son and he wants to download an app. I have a mifi 2200 and he would be able to use this or the connection at school. I don't want to just try it because it will be expensive if I have to pay for MB individually.
