The Blokket is just about the most stupid, wrong-headed case I have seen in a while. It certainly looks nice enough, and I’d probably use it based on its cute tool-bag styling alone. But the case also blocks cell signals, letting you “turn off distractions” for a moment. I hope you like dead batteries.

I bet you didn’t consider this feature when deciding between an iPhone 4S and an Android device such as the Galaxy S III. The company behind the radiation measurement app Tawkon has released a semi-disturbing infograph (which can be found at the bottom of this post) detailing the SAR (a measure of the rate at which energy is absorbed by the body when exposed to a radio frequency(RF) electromagnetic field) score of various popular smartphones.

Ever noticed that slapping a case on your iPad somewhat restricts its 3G signal? That’s because your iPad is equipped with a clever proximity sensor that reduces the power of its 3G sensor by as much as 75% when it detects your device is close to your body, thereby reducing your exposure to harmful radiation.

Unfortunately the sensor isn’t clever enough to work out the difference between your body and a protective case, so as soon as it comes into contact with a case its 3G signal is restricted. However, this particular case from Pong Research not only prevents your iPad from limiting its 3G signal — giving you faster, more reliable data — but it also redistributes its radiation away from your body.

After the Fukushima disaster, bogus radiation testing apps abounded – now Scosche has launched what it’s calling a true pocket radiation tester for your iPhone or iPod Touch.

The portable radiation sniffer called  RDTX-PRO, priced at $350, might cost more than your device, but it looks like it’s a hit. Launched yesterday, at this writing it’s already out of stock on the company website.
