What does the number of bars displayed on the phone really mean. Not much at all. Read more here.
Cell phone, mobile phones, and cordless phones produce both magnetic fields and radiowaves (microwaves). Most cell phone shielding devices are designed to reduce the radiowaves. But you can test for either, if you wish. The tricky part about measuring the radiation from a cell phone is that the emission strength varies widely over time. There will be strong bursts of varying intensity, followed by quiet periods. This makes it hard to compare "apples to apples". Also, because you are measuring up close to the source, you must use a near field meter AND you must maintain the position of the meter very precisely. First, you must have a proper meter. To check for magnetic field emissions, an AC Gaussmeter will work. Most AC gaussmeters will have an internal probe. Simply position the gaussmeter on the phone. Note carefully where the meter is positioned. Make a call and watch the readings. Notice the highest and lowest readings, and make a mental note of the "average" reading. Now, insert the magnetic shield, and repeat.
In general, you will not be able to completely kill a cell phone signal, unless you use extraordinary measures to attenuate the signal. With a good connection, you will need an enclosure which provides a million-to-one reduction or better to prevent the phone from connecting.
"Minimizes Radiation to the Head Area" If you read the fine print that comes with your cell phone, you will see that even the manufacturer warns NOT to put the phone up to your head. Radiation levels near the phone can be quite high. Using a headset to increase the distance from the phone to your head dramatically reduces your radiation exposure.
Using an AIR TUBE headset has these additional advantages:
Simple ear-bud style with soft rubber cushions give good fit and excellent sound quality. Long 39 inch cord with built-in microphone. Works with most phone models. Better than speaker phone mode as you can enjoy more privacy and put the phone down. Great for home or work, listening to music, games, and of course… phone calls! Patented. Check which plug style you need:

Most cellphone shielding products are designed to reduce radiation to the user while still allowing the phone to function. This means that some radiation can still get to the phone… and some radiation can still get out of the phone! But sometimes you need to completely kill the signal. The RF Kill Box is a full-metal shielding jacket with very high shielding performance. You probably know that different phones have differing signal quality… depending on your carrier, your location, and your phone model. A strong signal is harder to kill. In our tests, 99% of the phones we tested would not function when in the Kill Box under any circumstances. The metal slip on cover is quick and easy to use and provides a good seal. Inside diameter is 95mm (3 3/4”) and the height is 170 mm (6 5/8”). Large enough to hold most phones, but check your dimensions.
RF Kill Box (Cat. #A316) .............. $18.65
RF Kill Box Bulk Pack:
Who wants to make his own shielded passport or credit card sleeve? Or line a purse, wallet, cellphone case or backpack? Add a shielding liner to a pocket? Wrap a wifi node to block radiation output? Repair a fencing lame? Shield a part of a circuit board? Make an RF gasket? Shield your homeopathy bottles? Attach a ground cord to a fabric? There are hundreds of uses for this versatile shielding patch. A peel-off paper backing reveals a super strong conductive adhesive that keeps the patch where you put it. Easily cut to any shape with ordinary scissors, this metalized fabric is conductive on both sides, completely flexible with no stretch, and solid black in color. 40-50 dB from 10 MHz to 10 GHz. You get two pieces, each 5.5x8 inches. Not intended to adhere directly to skin. Do not machine wash.

Light Duty Economy Magnetic Shielding Mobile phones produce magnetic fields as well as the radiofrequency signal. Some customers have reported to us that they suspect it is the magnetic field which causes the burning sensation in their hand when they hold a phone. PaperSHIELD is the perfect solution! Only 0.010 inch thick, PaperSHIELD is flexible and can be easily cut with a scissors and shaped by hand into simple or very complex shapes. High saturation and moderate permeability make this ideal for shielding weak magnets, or stronger magnets with many layers of shielding. This material is particularly suited for achieving precise levels of partial shielding as you can add exactly the right number of layers to achieve the desired result. White paper on one side can be imprinted (by you). Peel and stick adhesive on the other side permits easy and semi-permanent mounting almost anywhere. Magnets will stick to it nicely. Bonus application! In addition to shielding magnetic fields, PaperSHIELD is also quite good at shielding radiowaves (cellphone, wifi, etc). And because of the adhesive backing, it can be adhered to almost any surface you need such as the inside or back of your cellphone case. (Use a near field meter to test RF shielding performance.) Note that it is not transparent, so it can't be used on the touch screen side. Cover the cut edges with sturdy tape as they can be sharp. 36 inches wide. Made in USA.

"Reflects up to 99% of Microwave Radiation Away from Your Body" So you are careful about NOT putting your radiation emitting mobile near your head. That’s good. But think about this: what body parts get the radiation when you put the thing on your pocket, bra, hat, purse, holster or elsewhere on your body? Now your vital and sometimes private organs are basically in contact with the source of the microwaves, getting the largest dose possible. Pocket Sticker is a high performance shielding patch that you stick onto your clothing which reflects that radiation away from your body. Simply invert the pocket, trim that patch to size if needed, peel and stick into place. Nothing to remember and nothing to lose. Just make sure the patch is positioned between you and the phone. Laboratory tested, the Pocket Sticker deflects up to 99% of cell phone radiation away from the body.
Can be used in jacket, shirt or pants pockets, holsters, bras, purses and other places where you keep your phone.

"Dual-Pouch Shielded Bag" Mobile Phone Pod is a handsome pouch for your mobile phone. Like others, it protects your phone from bumps and scratches. Unlike others, it comes with two distinct shielded compartments: One compartment is RF shielded on all sides. The other is shielded on one side. Let’s say you are in class, or at the movies, and you don’t want your phone to ring. Slip it into the fully shielded slot. In this position, RF signals in or out will be reduced almost to zero, which is enough to stop the phone from ringing in most circumstances unless you have an especially good connection. You can also store chipped cards (like credit cards) in here to prevent unintentional reading. In other circumstances, you may want the phone to be ready to receive calls or text messages… but you don’t want the radiation. Place the phone in the slot with one side shielded. As long as the shield is between your body and the phone, the phone can still work and you get less radiation. Perfect in your pocket or purse. Simple fold-over top with Velcro closure. Compartment measures a generous 10 x 15cm (4x6 inches) which will easily fit most phones and iPods. Durable black or white leather-like finish.
Mobile Phone Pod:
