Apple may unveil at least one model of its highly-anticipated iPhone 6 in the first half September, ahead of a commercial launch on Sept. 19.

The iPhone 6 has leaked extensively as of late, as the rumor mill keeps churning in anticipation of the first iPhone with a notably larger screen. Various reports have tried to paint a picture of what to expect in terms of specs and features, while others speculate on the smartphone's launch date.

The rumor that seems most likely to be accurate pegs the iPhone 6 launch for Friday, Sept. 19, which would fall in line with Apple's previous launch schedules. The company typically releases new products on a Friday, in order to give consumers a full weekend to get to know the new gadget. If the iPhone 6 goes on sale on Sept. 19, Apple should make an official announcement 7-10 days before that.

Last year, for instance, Apple unveiled its latest iPhones on Sept. 10, and the handsets went on sale 10 days later, on Sept. 20. If the company follows a similar pattern this year, the iPhone 6 could make its official debut on Sept. 9, ahead of the Sept. 19 commercial launch.

According to a new report from MacRumors, citing a "reliable source," Apple plans to officially unveil the iPhone 6 in early September.

"Mass shipments of the iPhone 6 from China to the United States are expected to occur during the last two weeks of August and it is likely that Apple will announce the iPhone 6 during the first or second weeks of September," MacRumors reports. "The first deliveries of the device will come later in the month on a corresponding Friday, roughly a week and a half after the event."

Judging by previous schedules and the purported Sept. 19 commercial availability, Sept. 9 seems the most likely date for the unveiling. Apple usually announces and starts taking pre-orders for its latest iPhone 7 to 10 days before it hits the stores, so a Sept. 9 unveiling would give it plenty of time to take pre-orders before the retail launch.

Apple is widely expected to introduce two new iPhone 6 models this year, one with a 4.7-inch screen and the other with a massive 5.5-inch display, purportedly called the "iPhone Air." It remains unclear at this point, however, whether the two models would launch at the same time.

Some early reports suggested that Apple had encountered some issues with the production of the 5.5-inch model and would delay the launch. Subsequent reports later claimed that the company had resolved those issues and the 5.5-inch iPhone 6 would launch alongside the 4.7-inch model, with no delays.

Both models will launch with the latest iOS 8 on board, and notable improvements are expected on all fronts. Rumored specs and features include a powerful Apple A8 processor, improved Touch ID fingerprint scanner, enhanced 4G LTE, wireless charging capabilities, NFC, and more.

Nevertheless, it's all in the rumor state for now, therefore it is highly advisable to take all leaks, rumors, and reports with a hefty grain of salt until official confirmation. We'll keep you up to date as soon as more information becomes available.
