I have an unlimited data plan. However, recently it seems like my browser, youtube and netflix apps are all running extremely slow (or not at all at times). I have a friend who is with AT&T who also has an unlimited data plan but when he hits a certain amount of data, AT&T "dials back" or slows his data functionality, making apps and all things that relate to data usage run slow. Does anyone know if Verizon does that as well?
