iPhone 4S set to become best-seller

It may only be days since the announcement of the iPhone 4S but reports suggest that the latest iteration of the handset is already on course to break sales records.

Unveiled only last week, the iPhone 4S received pre-orders via AT&T to the tune of 200,000 in the first 12 hours alone.

Meanwhile, Apple has announced that orders it receives now will not land on launch day (14 October 14), but will instead ship within one to two weeks, suggesting it has been inundated with demand for the latest device.

Total orders from all channels would easily put the iPhone 4S on course to trump the 600,000 units of the iPhone 4 ordered within 24 hours of the iPhone 4 pre-sale starting.

Could it be Appleā€™s best-seller yet?
