Next Apple iPhone rumoured to arrive on 25 September with pre-orders beginning on 18 September

Amid speculation hinting at the next iteration of Apple iPhone being released in 2015, a new report claims that the future iPhone 6 edition will be launched as soon as 25 September.

According to a Business Insider report, quoting a post in Mobile News (a UK blog) the next iteration of Apple's iPhone handset will be released on 25 September.

To substantiate this statement, Mobile News blog quotes an email, that it claims to have seen, by Vodafone UK to its staff, which has apparently indicated that the new iPhone will be released to the public on 25 September with pre-orders for this device beginning from 18 September 2015.

The above information looks promising as Apple, in the past, has launched multiple flagship smartphones during the month of September.

However, Mobile News fails to provide any information regarding the nomenclature of the next iteration of Apple iPhone, as the email reportedly refers to the new iPhone handset as just a "new iPhone".

Nonetheless, previously surfaced rumours have hinted at the next iteration of the iPhone being called iPhone 6S, more than iPhone 7.

As for the technical specifications of the next iPhone iteration, the handset is rumoured to feature a 2GB RAM which is in stark contrast to the current-gen iPhone 6 and iPhone 6 plus, both of which incorporate only 1GB RAM.

Reports also suggest that the iPhone 6S could be shipped with a pre-installed Apple SIM (universal SIM card). Apple SIM currently features in the iPad Air 2 that was released in October 2014 in the US and UK. With an Apple SIM pre-installed, users can choose from a host of available carrier options, rather than having to sign up with a particular operator's contract.
