Another day, another next generation iPhone prediction. This one seems to make sense, at lease based upon historical Apple iOS event dates and iPhone hardware announcements. Analyst Gene Munster with Piper Jaffray calculated the number of days between these two events for the past three years. Also listed in the chart below from AppleInsider is the actual iPhone ship date.
Extrapolating these numbers based on this year's iOS event in San Francisco scheduled for June 6 points to an August 24 iPhone 5 or iPhone 4S announcement. This would place the shipping date for the new hardware squarely in the middle of September. These predictions mesh well with previous information we've heard over the past few months.
