What network does 3 run on?

Other uses:
Magnifying glass.
Bulky endoscope for reading appliance serial numbers in hard to reach places (used only this week), or checking gas or electric meters against bills.
Torch.

Again, no need! I have 'special' eyes.

(I can read the serial numbers on the face of my watch - about 0.333 mm height - with my unaided eyes)

But I am sure smart phones really are jolly useful.

Ah but with an endoscope you could read them when the watch was down a drain
I do use my endoscope plugged in to my phone quite a bit

Go on, really impress me. Tell me how you can use a smart phone for a DIY colonoscopy!

1) Choose a comfortable model from here:

To clarify, My arms do not have eyes upon the ends. The fridge serial number was on the back. Gap not big enough for upper body to get eyes near.
Solution, stick arm down back and take photo with phone.

Likewise, take photo of small print on medicine bottle. Zoom in to read. Very useful if it's eye drops for glaucoma.

Of course these tasks are not actually possible, as they are not possible with a Nokia 1100 such as Xfool has.

Those of us with cameras upon our phones use them for a stunning range of uses.

See an advert for someone who fits gates, take a photo, it's quicker than finding pen and pencil.
Measuring something, rather than make a note, take a photo of the measure. You are going to have your phone with you when you need the measurement.
Checking my phone it has such riveting photo's as bread dough before rise, with tape measure and Ski boot (with size).

Those of us who always have our smart phone on us find that they often use the torch rather than struggle in a dark corner or hunt down a torch.

This is of course totally ignores the QR codes that you may come across in your travels.

As I said, you only realize the advantages once you use one for a significant amount of time.

Ps as servodude says, they also act as a small portable screen and capture mechanism for endoscopes used to inspect pipes or cavity walls, microscopes etc and can control professional cameras stuck on the end of very long poles to take areal photos without the need for a drone license or flight permission (Yes my brother uses such a rig). You can also use them as a screen for car diagnostic tools using the CAN interface. But most of us don't have such exotic uses.
