No one said they did. The suggestion is that the iPhone 4 was a watershed in cameras on smartphones. For a while the iPhone was considered the benchmark, and still is in many ways. As ever, the bigger number of pixels that other devices have does not necessarily mean better cameras. Optics play a huge role. Other mobile devices have caught up and some have exceeded the quality of the iPhones camera, but that doesn't change the fact that the iPhone 4 was an important milestone for smartphone photography.

Whilst it was the first iPhone to use a contemporaneous sensor, rather than cost-saving with previous-gen, it was still only a 5MP OmniVision OV5642 at the same time as Sony was installing 8MP sensors of a similar backlit configuration.

Ironically Apple switched to using Sony's Exmor sensors for later models.

How? Did t68i even come with a camera?

It did, literally, come along with a camera. You plugged the camera in to the charging socket. The photos were terrible: not even 256 colours, resolution in the order of 200 x 300. I used it twice and packed it away forever.

It was an attachment that plugged in the bottom of the phone. I don't remember being particularly impressed by the quality of the photos. It was getting chucked in with the phone eventually
