While Apple may tinker with the final packaging and design of the final phone, it’s clear that the features in this lost-and-found next-generation iPhone are drastically new and drastically different from what came before. Here’s the detailed list of our findings:

What’s new

• Front-facing video chat camera
• Improved regular back-camera (the lens is quite noticeably larger than the iPhone 3GS)
• Camera flash
• Micro-SIM instead of standard SIM (like the iPad)
• Improved display. It’s unclear if it’s the 960×640 display thrown around before—it certainly looks like it, with the “Connect to iTunes” screen displaying much higher resolution than on a 3GS.
• What looks to be a secondary mic for noise cancellation, at the top, next to the headphone jack
• Split buttons for volume
• Power, mute, and volume buttons are all metallic

What’s changed

• The back is entirely flat, made of either glass (more likely) or ceramic or shiny plastic in order for the cell signal to poke through. Tapping on the back makes a more hollow and higher pitched sound compared to tapping on the glass on the front/screen, but that could just be the orientation of components inside making for a different sound
• An aluminum border going completely around the outside
• Slightly smaller screen than the 3GS (but seemingly higher resolution)
• Everything is more squared off
• 3 grams heavier
• 16% Larger battery
• Internals components are shrunken, miniaturized and reduced to make room for the larger battery

Retina display

The Retina display on iPhone 4 is the sharpest, most vibrant, highest-resolution phone screen ever, with four times the pixel count of previous iPhone models. In fact, the pixel density is so high that the human eye is unable to distinguish individual pixels. Which makes text amazingly crisp and images stunningly sharp.

multitasking

iPhone 4 introduces a whole new way of multitasking. Now you can run your favourite third-party apps — and switch between them instantly — without slowing down the performance of the foreground app or draining the battery unnecessarily.¹ This smarter approach to multitasking is available only on iPhone.

Shoot your own movies in high definition. Capture impressive video even in low-light settings, thanks to the advanced backside illumination sensor and built-in LED light. Then edit and create your own mini-masterpiece right on iPhone 4 using the new iMovie app — with Apple-designed themes, titles and transitions. It’s coming soon to the App Store.

Take beautiful, detailed photos with the new 5-megapixel camera with built-in LED flash. The advanced backside illumination sensor captures great pictures even in low light. And the new front-facing camera makes it easy to take self-portraits.

HTC Evolve concept tablet, created by Timur Pinar. The device runs Android OS, comes with a stylus pen and an extra OLED touchscreen plus side pre-programmable buttons, for extra functions.

HTC Evolve features an Intel Atom CPU, a touchscreen display, 128GB SSD, 1.5GB of RAM memory, a custom skin for Android and compatibility with Chrome OS. On board of the concept tablet you’ll also find 2 USB 3.0 ports, a HDMI port and a 3.5mm audio jack on the right side.

You’ll find a camera and microphone embedded in the front bezel of Evolve, for video communication. Will Apple be able to match this design?

We’ve seen quite a bunch of transparent phone designs lately, but none of them had the Nokia brand on. Luckily, designer Juan Carlos Garzon created one such Nokia concept, with a touchscreen interface and a transparent display.

The lower side of the handset includes the battery, most of the hardware, incorporates the on/off button (front side) and a 5 megapixel camera (at the back). This Nokia concept’s display also emits light, allowing for better usage during night time.

A stunning design and a great idea!
