Rent Pulse (2006)

The year's most original horror film, Pulse takes fear into new territory - the very devices we trust to get us through the day. When the dead discover a means to contact the living through electronic devices, cell-phones and computers become open gateways to monstrosities and destruction. Starring Kristen Bell, Christina Milian, Ian Somerhalder and Rick Gonzalez, Pulse is loaded with terrifying thrills and gruesome special effects, and capped with an astonishing surprise ending.
