Tech: If you’re on AT&T with your iPhone, your 3G will go faster soon

  • AT&T is upgrading their network, with a nationwide rollout soon. 3G speeds are pretty fast, but it could be faster. As a result, the phone company is adding speed upgrades which should boost the already zippy theoretical speed from 1.7 Mbps to 3.6Mbps. But those numbers are misleading – real world usage is currently about 700Kbps. The boost should hit by the end of the year in most markets, and AT&T is also working on a 4G network. As long as we can use our hacked iPhones to download torrents, we’re happy. source

Tech: Want to secure your wi-fi? Paint your office.

  • That’s what Japanese scientists say. It’s a pain in the butt to block wireless signals from the outside world if you’re the IT guy, but apparently, if your office’s paint job contains the right material (by adding certain metals), it can block those signals for reaching beyond the current room. And unlike other signal-blocking solutions, it’s actually kinda cheap to make. Neat. source
