A "citizen journalist" on CNN's iReport site is saying that Apple chief Steve Jobs was rushed to the ER a few hours ago with a heart attack. So far the rumor appears to be unconfirmed by any other major news sites. "I have an insider who tells me that paramedics were called after Steve claimed to be suffering from severe chest pains and shortness of breath," they write. The Unofficial Apple Weblog, meanwhile, says via Twitter (techie!) that Apple PR says Jobs is fine [UPDATE: Untrustworthy Apple flack also reassures Valleywag].We won't believe it till they trot him out for the cameras. Full citizen report below [UPDATE 2: and a statement from CNN Worldwide debunking it as a hoax]:
