EMFs from cellphones

Can a cellphone be put in EMF-blocking film/coating/case and still function well?

Do new cells with slower memory & CPU, dimmer screen emit less EMFs than older but faster memory & CPU and brighter screen?

Does newer tech in general emit less EMFs?

Are there clothes (for humans) and accessories (like special glasses, lenses) which blocks EMFs?

I've read that rolling around in grass and holding one's hand under water reduces EMFs or something. True or not?

I've also read cells (and electronics in general) shouldn't not just be turned off but also unplugged when one isn't going to be using them for a while yet be around them. True?

If a cell is turned off for hours though, will that prevent it fro receiving SMS, mails, etc?

Should one position one's bed at least 6 inches from the wall due to the wall containing electrical wirings?

I think a lot of the hype over cell phones and EMFs are overrexagerrated, seriously. Perhaps if you held it by your ear for 24/7 for years it might cause issues (I do know people that do that) but I dont think theyre nearly as dangerous as some make it out to be. As far as the radio signals, slower CPUs and such probably wont make a difference, I suspect its the signal it puts out thats considered "dangerous." and rolling in grass? pffft if you want to roll around in your front yard be my guest. And my phone is on 24/7-it needs to be. they will still get emails and whatnot when turned off but you wont receive them till you turn it on (obviously) and six inches from a wall? lol. again knock yourself out, I don't have that much free room to play with. What Im saying is-a lot of these concerns are way overrexaggerated, and not nearly as dangerous as some may think.
