As anticipation for the unveiling of the iPhone 5S heats up, there are plenty of rumors still swirling. So what does everyone have to say about it? Here are some of the latest expectations some are reporting about when it comes to the iPhone 5S.

iPhone 5S

iPhone 5S, not iPhone 6

First, let’s start with the name. It appears as if expectations have finally shifted from a major overhaul worth of the iPhone 6 name to a minor S upgrade. The Japanese tech site Macotakara, which has a fairly good track record in terms of foretelling what Apple Inc. (NASDAQ:AAPL) will do, claims that a source within the industry has confirmed that the next iPhone will be called the iPhone 5S. The report also indicates that we will see an iPhone 5C along with the iPhone 5S and that the 5C will be the low cost plastic model of the iPhone.

Unveiling Sept. 10, Launch Sept. 20

And of course everyone wants to know when the iPhone 5S will be out. Apple Inc. (NASDAQ:AAPL) is expected to introduce its next generation iPhone (iPhone 6 or iPhone 5G) in a special event scheduled for September 10, according to Ina Fried of AllThingsD. And then it could go up for sale 10 days later—on Sept. 20, according to Steve Kovach from Business Insider.

He explained the details behind his prediction: “Historically, Apple Inc. (NASDAQ:AAPL) has launched new products on Fridays. However, it also likes to make sure reviews for the new product are published before the launch. So, here’s what will probably happen. As it always does, Apple Inc. (NASDAQ:AAPL) will give a select group of tech journalists the new iPhone to review following its announcement on September 10.”

Tech writers and journalists have to agree not to write about certain devices until a certain point or date. Typically, that restriction ends at 9:00 pm Eastern Standard Time on a Tuesday when Walt Mossberg for AllThingsD publishes a weekly column. It’s predicted that the chosen tech writers will have to wait to share their reviews on September 17th in order to maintain the tradition of the September 20th launch.

iPhone 5S with fingerprint sensor

And finally, the most-talked about feature of the iPhone 5S is the fingerprint sensor, which appears to be giving Apple Inc. (NASDAQ:AAPL) some major problems. As such, supply of the new handset may be limited, according to DigiTimes.

According to the site’s latest report, Apple Inc. (NASDAQ:AAPL) will only be able to ship 3 million to 4 million iPhone 5S handsets by the end of September. Originally, the company wanted to ship 10 million iPhone 5S handsets right out of the gate. The newspaper said that specifically, there are problems with the integration between the A7 chips and the fingerprint sensor.

DigiTimes also said low yield rates at the packaging company Xintec are causing supply constraints. It indicated that an engineering team has been sent to Xintec to help ramp up the yield rate and that Apple Inc. (NASDAQ:AAPL)’s iPhone 5S supply chain will be able to begin volume production of fingerprint chips at the end of this month.
