Pong Radiation Protection Case

I just saw this case and was interested in it and thought I'd ask the forum if anyone knows anything good or bad about it, or perhaps has one for their iPhone. I am concerned about the radiation issue associated with the iPhone as from the SAR list, it is pretty significant.

Would appreciate any feedback on this case.

Blessings,

"Pong is the first product to meet international testing standards for SAR reduction and has been verified by industry leading laboratory Cetecom to reduce SAR for the iPhone 3GS in the WCDMA 1900 by over 60%."

Here is the problem, the iPhone does not have a CDMA radio, it is GSM. So they didn't get that right. Also unless it has some sort of stealth technology you can't manipulate electromagnetic radiation like this. You can reflect it off surfaces and absorb some, like stealth planes do, but you can't channel it. Especially the way their animation shows, there is nothing on the head side of the case to deflect it.

"TRP represents a cell phone's outgoing signal strength. With the Pong Case, TRP is 100% as compared to an iPhone 3GS without a case, as confirmed in tests by Cetecom (view PDF)."

The iPhone does not broadcast a signal, it only picks up the signal from the cell towers or wifi access points.

If you are worried use the speaker phone or the included headset.

Well, yes and no. EDGE is GSM, but AT&T's 3G (UMTS/HSDPA) is a WCDMA protocol. Which has nothing to do with CDMA as practiced by Verizon and Sprint.

The iPhone and all other phones most certainly do broadcast signals. Communication between a tower and a cell phone is a two-way process carrying both the transmission of voice and data to the phone as well as the transmission of voice and data from the phone.

My RF engineer buddy has one of the Pong Research cases and swears by it. He says the science is legit, especially since it's backed up by the top testing lab in Silicon Valley that all the handset mfg's use. Even if it is the only real technology out there that can cut down on radiation (all those stickers and absorbers are bogus), the question still remains, just how dangerous is cell phone radiation?
