Hello, Could someone please tell me which android phones (Droid, Samsung Moment, Cliq, etc) will work without a service plan (both voice and data). I am a graduate student in Computer Science and want to use an android phone for a research project. I will be using the phone as a computer (using the camera, running my app, etc) and not as a phone. Purchasing the phone without a contract will not be an issue. I have tried to search the forums and also called up customer service reps of the various phone companies but couldn't get a satisfactory answer. Thanks for your help in advance.
