The Great Measures Apple Took to Keep Verizon iPhone a Secret

Guest Author ∙ Updated March 18, 2019

Although the iPhone 4 was already 7 months old when it launched on the Verizon network, Apple still went to great lengths to keep the CDMA version of the device a secret. Learning from its mistakes it made with the iPhone 4 prototype last year, Apple set strict rules and implemented tight security measures to ensure it didn't happen again.

Verizon staff weren't authorized to field test the device until just two weeks before its launch, after signing non-disclosure agreements promising they wouldn't let details slip. Those entrusted to test the device weren't allowed to call it an "iPhone" – it was given the code-name "ACME" and that's what it had to be called…

Sébastien Page ∙ Updated August 12, 2017

iDB readers that don't live in India (that would be 99% of you) might just want to skip this post, unless you want to learn about an interesting subsidy model this Indian carrier is using.

I often get emails from Indian readers complaining about Apple not selling the iPhone 4 in India. As powerless as I am, my only response usually is "I'm sorry but there is nothing I can do". Today, I'm glad to report to our Indian readers that the iPhone 4 is finally making its way to India.

According to TUAW, the iPhone 4 is going to hit the Indian market this Friday, May 27th, compliments of local carrier Aircel...

i3D – the 3D Head-tracking Project Turned App

Cody Lee ∙ Updated January 24, 2016

Remember back in early April when we posted a video of that impressive 3D demo? Well, it seems like the developers were able to turn that project into an actual iOS application.

Before you get too excited, you should know that the software is pretty limited. It really isn't much more than a showcase for the 3D technology that was shown in the popular video released last month...

iPhone 4 Wins “Display of the Year” Award

Alex Heath ∙ Updated December 26, 2016

We all love the iPhone 4's brilliant retina display. When Apple introduced their ground-breaking, 640x960 display during the iPhone 4's launch event, the rest of the mobile display market was left in the dust. After all, how can you compete with a screen that matches the same pixel density perceivable by the human eye?

Besides the obvious appeal to consumers, the retina display has also garnered Apple the "Display of the Year Gold Award" from The Society for Information Display...

iPhone 4 Uses Same Noise Cancelation Technology as Google Nexus One

Alex Heath ∙ Updated November 13, 2019

Who would have seen that coming? It turns out that the iPhone 4 and Google Nexus One share the same noise cancelation technology. The A1026 chip by Audience has finally been discovered as the technology behind the iPhone 4's impressive noise cancelation.

While also demonstrating that the iPhone can never be dissected too much, the folks at iFixit have finally uncovered the magic of the device's low power audio signal processor. Noise cancelation helps remove ambient and unwanted noise when the iPhone's mic is turned on.

Alex Heath ∙ May 18, 2011

Apple has slowed production and lowered its expected shipment volume of the GSM and CDMA iPhone 4. This move is expected to correlate with a new iPhone release in September, with production of the new device starting in August.

The dubbed 'iPhone 4S' is expected to have an 8 megapixel camera made by OmniVision and Largan Precision. It is also rumored to sport a A5 dual-core processor with support for T-Mobile and Sprint...

RecognizeMe Allows for Biometric Facial Recognition on a Jailbroken iPhone

Alex Heath ∙ May 18, 2011

In case you needed one more reason to jailbreak your iPhone, try this on for size: biometric facial recognition. Instead of unlocking your iPhone with a simple password (How boring is that?), you can use the iPhone 4's front-facing camera to scan and recognize your face.

RecognizeMe is a new jailbreak app that helps make your iPhone safe from shady characters and potential homescreen peekers. By matching your face to a pre-defined database, RecognizeMe will unlock your iPhone and give you access to your device.

Following yesterday's news regarding the leaked iPhone 5/iPhone 4S components, comes additional "leaked" parts for the next-generation iPhone.

The latest leak comes courtesy of the folks over at Apple.pro, who have had a good track record with Apple leaks in the past.

Labor and Materials Shortages Could Impact iPhone 4 Shipments

Cody Lee ∙ May 12, 2011

If you are currently sporting an iPhone 3GS or older model and are thinking you might not be able to hold out for the next product refresh, you may want to grab an iPhone 4 while it's still available.

DigiTimes is reporting that Taiwan-based manufacturing firm Foxconn is facing a shortage of both labor and materials at its China plants. This will likely affect shipments of Apple's new iPad 2 tablet and the popular iPhone 4...

Hot Shoe Holder Puts Your iPhone 4 and Your DSLR on the Same Team

Jeff Benjamin ∙ Updated February 18, 2018

Being an avid photographer and cameraman, I was pretty excited when the opportunity to review the Hot Shoe Holder presented itself.

For those of you who aren't camera geeks, the hot shoe is that little metal plate that sits on top of a camera. It's used to mount peripherals (mainly flashes), and while you won't normally find them on point and shoot cameras, they're staples for DSLRs.

That brings us to the Hot Shoe Holder, a small plastic iPhone 4 holder that allows you to mount your iPhone onto your camera's hot shoe.

If you're into photography, no-doubt your wheels are already spinning at the possibilities, while non-camera folks might start scratching their heads.

Why would you want to mount an iPhone 4 on top of a camera? Folks, the possibilities are almost limitless...

The Olloclip is a Multi-Purpose Clip-on Lens for Your iPhone

Cody Lee ∙ Updated September 20, 2016

It's no secret that the iPhone is the most popular camera in the world. The new iPhone 4's 5 MP shooter is pretty solid when it comes to mobile phone cameras, but unlike standalone picture-takers, it doesn't have many options to tweak. There's no white balance or shutter settings, and no interchangeable lenses.

Patrick O'Neil and Chong Pak are looking to change that with their olloclip accessory. The tiny lens just slides on your iPhone 4, instantly giving you the ability to shoot fisheye, wide angle, and macro photos...

Report Claims iPhone 3GS is Outselling Flagship Android Phones

Cody Lee ∙ May 9, 2011

While the iPhone continues to be widely popular, each new device launch seems to come with a large amount of criticism. The original iPhone didn't have a cut and paste feature, the 3G didn't have video recording, and the 3GS only had a 3.2 MP camera without a flash.

Although its specs aren't always cutting edge compared to its Android counterparts, the iPhone has been a handheld favorite since its inception. This fact is reiterated by a recent report that not only is the iPhone 4 the top selling smartphone for Verizon and AT&T, the 3GS is outselling top Android phones...
