Sony and AT&T Wireless are teaming up to bring you…GhostBusters.This is kind of a good-news, bad-news story. The good news is that Sony Pictures Television will be the first Hollywood studio to offer full-length movies on your AT&T cell phone. In May, they will launch the service, and the company says that it will offer a “wide-range” of popular titles. The company noted that the titles will be streamed with advertisements.
