In a bid to further appease the iPhone 4 antenna debacle, Apple has released images of its high-tech phone test labs.
Numerous reports have surfaced of the iPhone 4 dropping calls when being held a certain way due to it having an external antenna.
The phone was released in the US earlier this month.
In a press conference last week, Apple CEO, Steve Jobs, announced it was giving away free cases to people that bought the device before September 30 as a way of fixing the issue.
According to Apple’s official website, the company spent more than $100 million building the “advanced antenna design and testing facility”.
Engineers were said to have “logged thousands of hours” designing and testing the iPhone 4 in the facilities.
The labs feature 17 antenna characterisation chambers to measure antenna and wireless performance, according to Apple.
The vendor also claimed to have tested the phone in a variety of real-world situations. “iPhone 4 was field-tested in nearly every possible coverage scenario across different vendor and carrier equipment all over the world,” the website said. Apple’s iPhone 4 will be released in Australia on July 30.
