Apple's iPhone 6S, 6S Plus, launched on 9 September in San Francisco, can now be pre-ordered at Apple's online stores in US, UK, France, Germany, New Zealand, Japan, Hong Kong and Japan. However, shipping dates of pre-orders have now slipped.

According to a MacRumours report, the Rose Gold colour variant of the iPhone 6S, 6S Plus has been hit by delays in the United States, and the latest shipping window is now between two and three weeks across the country. Shipments of other colour variants of the new iPhones are also said to have slipped by an identical two to three weeks.

MacRumours also states that customers in the UK, Australia and Germany who have pre-ordered Apple's latest iPhones should also expect shipments to be delivered in two to three weeks, with the exception of a few models in other colours. Like in the US, the Rose Gold variant is again said to be the victim of shipping delays.

However, Apple's official website still lists the delivery date (of pre-orders) as 25 September. Customers who have pre-ordered the iPhone 6S/6S Plus can let us know when they receive their orders.

Nonetheless, with Apple expected to begin retail sales in physical outlets from 25 September, prospective buyers can still try to procure the new smartphones. Stocks are expected to be limited considering the increased demand for both the new handsets.

A SIM-free variant of Apple's iPhone 6S Plus can be procured in the US for a starting price of $649. The handset's price in the UK starts from £539.
