Researchers at Stanford University have discovered a way to create two way communication over the same radio frequency. This is big news since it could lead to doubling Wi-Fi and mobile phone network speeds. That’s something we can all appreciate.

The new research makes us completely rethink how wireless networks can be designed. Unlike radio it has the ability to receive and transmit at the same time, so it can mimic the way humans screen out the sound of our own voices during a conversation. It uses two transmitters in the hardware at both ends of the conversation, with the two transmitters working in a similar way to noise-cancelling headphones.

There’s a whole industry built around extending your iPhone 4s battery life, since it isn’t replaceable like the Galaxy S. Here’s the latest device to get your iPhone all juiced up, the latest case with an extended battery pack.

The Mili PowerSpring 4 ships today for £54.99 (or $85 on Amazon). The company claims that it’s the world’s thinnest iPhone 4 battery pack to double your battery life thanks to a 1600mAh capacity Li-Pol battery.

This has got to be one of the ugliest iPod docks we’ve ever seen. Obviously it’s made from some rusty old electrical industrial parts. The product page says it will make a great engagement or wedding present. But that’s only true if you’re a redneck.

But hey, it does support two Apple devices instead of one. It’s compatible with any generation of the iPod or iPhone and even the Nano. Do you want one?

The S in iPhone 3G S means more than just faster 3G speeds, which is now 7.2 mbps, for the new iPhone. It also means a faster processor. But just how fast is the iPhone 3G S?

Well, thanks to T-Mobile we have the first official word on the iPhone 3G S processor: 256 RAM (that’s double the iPhone 3G) and a 600 Mhz processor. The chip is most likely built using a 45nm process, but that’s just a guess.

The G1′s battery life isn’t as great as we would like, which is an issue with smartphones in general. That’s why this $17 device is a great idea. It will come in very handy for keeping your Android G1 powered at all times. It will charge your G1, plus there’s an extra dock to power a second battery, making it perfect for travelers who carry a spare battery. It’s a cheap way to make sure you always have some precious juice.

The Ant Commandos Double Range Guitar sells for $59.99 and does double duty, since it can play both Guitar Hero and Rock Band in one guitar. The Double Range Guitar plays PS2 and PS3 versions of both Guitar Hero (I, II and III) and Rock Band.

It operates on 2.4GHz wireless technology with a belt clip that gives players unlimited freedom. All of the functionality is retained, like a second set of Rock Band solo buttons near the strum bar and distortion effects. This is a great option for those with limited space who want to play both games.
