Whiz
Whiz Wireless is a phone company that appears in GTA IV. It is a parody of Verizon Wireless. It competes with Tinkle for dominance in the wireless market, using the slogan "Whiz is stronger than Tinkle." The two names are slang terms for urine.
In the game, Niko Bellic starts with a Badger phone until Playboy X gives him a Whiz phone in the "Photo Shoot" mission to take a picture of a snitch. The new phone is both nicer looking than the old phone and has a Camera, allowing Niko to take pictures.
