I have a very basic question and I hope somebody can help me. I want to buy an unlocked Samsung Galaxy S phone and use it exclusive as a WiFi phone in the USA. Can I buy an unlocked phone and expected to work with WiFi without having to have an agreement with the phone companies? I don't mind paying $600+ for the phone, but it is the monthly fees from the phone companies that I would like to avoid. I am almost certain that this would work, but I just wanted to ask that question before I actually buy the phone. I want to make sure that the phone companies and/or Samsung have not done something that would prevent me from doing this without a contract. Thanks in advance for your help.
