Consumer technology giant Apple’s new iPhone will be named as iPhone 4S, but the much-expected iPhone 5 may arrive only in 2012.

Analyst Keith Bachman of BMO Capital Markets believes the new iPhone will be announced in the month of September and will be called iPhone 4S.
“We believe with the new iPhone release, Apple will offer 3 models - iPhone 4S, iPhone 4, and iPhone 3GS. Net, the iPhone 3GS will be the low-end phone, in our view,” Bachman said.
Bachman said the September iPhone will be an iPhone 4S, not an iPhone 5, meaning more evolutionary changes than revolutionary changes. He expects the device to features a better camera and a different case.
“We believe the iPhone 5 will launch in mid-2012,” Bachman wrote in a note to clients.
While there has been ongoing speculation that Apple could be adding Taiwan Semiconductor Manufacturing Company (TSMC) as a second SoC chip manufacturer in addition to Samsung for its future, next-generation ARM-based A6 chip, a new rumor has it that the iPhone- and iPad-maker may be severing ties with Samsung in favor of giving TSMC full exclusivity in manufacturing the chipsets that power the iPod Touch, iPad, and iPhone.
News that TSMC may be the sole exclusive manufacturer of the ARM-based A6 chip–the current iPad 2 utilizes a dual-core 1 GHz A5 chip while the iPhone 4 uses an single-core A4 chip–comes by way of a Merrill Lynch analyst in Taipei as well as a source from Ars Technica.
It is speculated that the move to give TSMC exclusive manufacturing of the A6 may be a result of Apple’s lawsuit against Samsung.
Manufacturing of the A6 chip could start sometime in 2012.
