iPhone 4S makes Smartphone Vendors Hold Back Launches until Q2

The release of the iPhone 4S in the fourth quarter of 2011, rather than earlier, has caused some disruption in the release calendars of other smartphone vendors, who want to avoid clashing with Apple's star handset that should remain at peak during the first quarter of 2012.

According to sources from smartphone supply chain partners, Daniel Shen and Adam Hwang from Taiwan-based Digitimes claim that Apple rivals like LG, Samsung, Nokia and HTC, are deliberately planning to release their handsets in the second quarter of the year, when iPhone 4S won't be so hot.

This could mean that there will be a larger number of models launched at Mobile World Congress later this month, as vendors try to make the most of the window ahead of the launch of the iPhone 5 later this year.

It has also been reported that at least one vendor, HTC, will release fewer number of handsets in an apparent bid to rationalise its supply chain, reduce confusion for prospective customers and improve its marketing message.

The iPhone 4S is enjoying record sales since it was launched in October last year, and this despite the fact that top of the range handsets from rivals feature superior hardware.
