iPhone 5 vs iPhone 4S in 3D concept video

How will the new iPhone 5 shape up compared to the iPhone 4S? Find out in this cool new concept video, which puts the two phones side-by-side and spins them every which way.

We've seen the inside and outside of the new iPhone as photos of components leak in dribs and drabs. But now they've been assembled in a video placing 3D models of the two phones side-by-side.

The good folks at 3D-desk.com, who create three-dimensional animated models for your perusal, drew on industry rumours, strategic logic -- and "a bit of wild guessing" -- to flesh out their hypothetical iPhone.

The video shows the difference in scale between the current model and the hotly anticipated new iPhone, including the new smaller dock connector and headphone jack moved to the bottom. Hit play below to see the two phones spinning in space without a care in the world:

Leaked photos reveal the new iPhone to be taller than the current model when you hold it normally, or wider when you turn it sideways to landscape orientation.

The screen will apparently measure 4 inches across and boast a resolution of 640x1,136 pixels with a 16:9 aspect ratio, meaning no more black bars when you watch movies and TV and allowing your video to make the most of the screen. The extra space on the screen is also enough for an extra row of icons on the home screen.

There's no guarantee this is what the new iPhone will look like, of course. In fact, the animated animators behind this video also speculate Apple could keep the screen the same, rather than forcing app developers to change the layout of apps.

If you're wondering what the new iPhone would look like if the screen stayed the same size and it just got thinner, check out this video:

What do you think of the look of the new iPhone? Are the expected changes smart thinking by Apple, or does the iPhone have other problems that haven't been addressed here? Tell me your thoughts in the comments or on our Facebook page.
