Just watched the official trailer for The Signal that was posted this morning on Apple.com, and it's brilliant! I love how it's full of violence & action, but doesn't give too much away about the movie like most trailers do these days! Even though The Signal's release date has been switched around a few times now, it's definitely hitting theaters on February 22. Soooo excited to finally check this one out! You can find the new trailer here:

Thank you for posting this link. My curiosity has definitely been aroused. I must see this film. I may be mistaken,but I believe a film adaptation of Stephen King's novel "Cell" is in the works. I have not read the novel,but from what I understand it has a similar plot.
