Rise of the Cybermen (1) - S2-E8
Corrected entry: When Rose's phone first connects to the Cybus network on the parallel Earth, the first thing that shows on the phone is a news broadcast, yet the bar at the top of the phone shows the filename "welcome.jpg". Jpeg is a static image format.
Correction: That's true in this universe, but they're on an alternate Earth and things are subtly different - Rose's father is alive, people refer to things differently, etc.
