There are not many companies in Silicon Valley that would take advice from former Apple CEO John Scully. After all, he was responsible for almost killing what is now one of the largest companies in the world. The lack of people listening is not stopping him from offering up advice.
In an interview with Bloomberg, the former CEO said that BlackBerry is at the point where it can still turn around, but it must stop building hardware. Sculley said that BlackBerry can "come back if they drop hardware and focus on secure messaging," although he also cautioned that "the clock is running out" on the company.
At this point, I'm not sure if anything can save BlackBerry. Instead of taking the proven road and developing a smartphone around Android and incorporating their corporate and messaging features, the decision to go it alone and create their own operating system most likely will be their downfall.
