Hello, I'm here to ask a question regarding my data plan and WiFi connection. First is, how do i turn off my internet data plan on my phone temporarily so i can test if my WiFi connection works. The second one is, will using WiFi connection affect my data plan usage? In other words, if i was watching youtube videos, or perhaps downloading apps through the app market, will it be using up my data plan if i was connected to the WiFi? I'm using a Droid X, via Verizon Data plan.
