Apple's new 4-inch iPhone has been pictured for the first time alongside an iPhone 5. The device looks just like an iPhone 6s, with rounded edges and 2.5D curved glass — but it carries a noticeably smaller display.

We may have already seen this iPhone before; a video that surfaced last week claimed to show off a 4-inch iPhone that had leaked off the production line — but there was no other iPhone in the video to confirm it was indeed smaller than a regular iPhone 6s.

In the image above, which was published on the One More Thing forum, where new Apple products — such as the iPad Air 2 — have been leaked ahead of their official debuts in the past, it's clear that the new device is indeed no bigger than a 4-inch iPhone 5.

This photo comes just days after a report from 9to5Mac claimed Apple will announce a 4-inch "iPhone 5se" sometimes this spring. The device is expected to feature an A8 processor, an M8 motion co-processor, Apple Pay with NFC connectivity, Touch ID, and support for Live Photos.

One big feature the iPhone 5se is likely to miss out on is 3D Touch, which was just introduced with the iPhone 6s and iPhone 6s Plus last September, and will likely remain exclusive to Apple's high-end devices for at least a couple of years.
