The iPhone 4S is available to buy online and in stores today, amid predictions that Apple could shift as many as four million units this weekend alone.
According to analyst Carl Howe of the Yankee Group, the long-awaited fifth-generation smartphone could more than double the 1.7 million opening-weekend sales the iPhone 4 posted in 2010.
Demand is likely to have been driven by the iPhone 4S’s lengthy gestation period, which means more consumers are out of contract and ready to upgrade.
The death of Apple founder Steve Jobs is also generating sales, as fanboys and mass-market buyers alike clamour to buy one the last products created on the company’s creative tyro’s watch.
Unlike models prior to the iPhone 4, the 4S is available across all major UK networks from launch, with the exception of Virgin Mobile which has yet to announce any plans to carry the handset.
Unveiled earlier this month, the latest Apple smartphone challenger retains the design of the iPhone 4 but boasts a substantially more powerful A5 processor and offers browsing speeds of up to 14.4Mb – double what its predecessor could offer.
Also on board is an eight-megapixel camera – up from five megapixels – and the headline-grabbing Siri advanced voice control app that enables users to make appointments, dictate text messages and conduct web searches just by using their voice.
