I was speaking to a friend of mine who deals with back pain and he mentioned that apparently he is getting more referrals from people who keep a mobile phone in their back pocket. It could be pressing against sciatic nerve. This is something that could effect more people then they realise over a period of time,

Plus, as I did once, you can also crack the screen

At a guess, I'd say my sciatic nerve is pretty well padded by my fat ass.

that and it being easier to nick. (just got back from notting hill carnival, nothing in the back pockets all day )

Yes, I wouldn't ever leave anything of value in my back pocket.

I was there too, but I'm a front pocket kind of guy! Phone home safe and sound!

The problem with the front pocket when you are working is that is liable to being banged and broken when carrying heavy items. Which is why I keep mine in a belt pouch on my hip when working.

Me too. Thank god for the amazing Orange Care. The guy from Orange actually told me not to say that I'd put it in my back pocket.

My screen always faces inwards!

If you're thumping yourself in the groin area with heavy objects, you might want to consider your local S&M club!

What about keeping it in your shirt pocket?

I too always keep the screen facing inwards.

This is true, also the case if you carry a wallet in your back pocket.

Credit cards in the back pocket can end up being a problem.
So a smartphone in there of course has a good chance of taking part in a smartphone recycling scheme.
