“Even though our sources still maintain that we will see an iPhone 5 this summer, many blogs are reporting that iPhone 5 won’t come to the market before Q4 2011,” Lalit Sharma reports for TechzTalk. “John Paczkowski of All Things Digital believes that Apple will announce iPhone 5 at its Fall Music Event and will ship it in Q4 of this year. Adding more fuel to the fire, Digitimes is reporting that Apple has yet not released production roadmap for iPhone 5 indicating delay in launch. Digitimes also adds that because suppliers have not received a timetable to stop current iPhone 4 production in preparation for the next generation of iPhone. The launch of iPhone 5 might be delayed until September, or even 2012.”

“However, our sources say that Apple has never stops production of older generation of iPhone even after launch of new iPhone,” Sharma reports. “For example, Apple is still producing and shipping iPhone 3GS, 10 months after iPhone 4 launch. In case of iPhone 4, Apple started a completely new production line at Foxconn for the new handset. Our sources further add that because iPhone 5 will see some major design tweaks like bigger screen and new chipset. Apple will have to definitely start a new production line, which they normally do about 1-2 months before shipping the new product.”

Sharma reports, “Most of these iPhone 5 rumors are based on guesstimations because analysts are not getting any information from Apple’s tight-lipped supply chain. Many analysts were releasing similar reports about delay in production of both iPhone 4 last year and recently released iPad 2, before Apple actually announced and shipped the new products on time. So we should take all these iPhone 5 delay rumors with a big grain of salt.”
