Apple plans to unveil its next generation iPhone next month, technology blog AllThingsD said Wednesday.

AllThingsD cautioned that Apple could "change its plans anytime," but said the present plan calls for Apple's new chief executive Tim Cook to preside over the launch of the iPhone 5 on October 4.

Jobs, 56, the Silicon Valley visionary behind the Macintosh computer, the iPod, iPhone and iPad, stepped down as Apple's CEO on August 24. Jobs has presided over Apple's splashy product launches in the past and AllThingsD said "the pressure will be on Cook to turn in a good performance."

Jobs underwent an operation for pancreatic cancer in 2004 and a liver transplant in 2009. Apple released the iPhone 4 in June 2010 and sold 20.34 million of the devices last quarter. Apple shares have been trading at record highs this week and the stock was up 1.37 percent at $419.13 on Wall Street on Wednesday.
