One of the latest surround sound formats that's generating lots of buzz among home theater enthusiasts is DTS-HD Master Audio. The DTS equivalent of the data compression-free Dolby TrueHD, it promises high-resolution multichannel audio comparable to the original master recording used in theaters and cineplexes.
Well, you can't say they didn't warn you.
Apple released an update for the iPhone on Thursday that brings the Wi-Fi Music Store to the device, as well as several security fixes and enhanced features. But, as expected, it also turns iPhones that were unlocked to run on cellular networks other than AT&T's into little more than emergency call boxes.
Macworld reported two iPhones in its office with SIM (subscriber identity module) hacks did not work after the update was installed. A message prompted the phone's owner to install "an unlocked and valid SIM card" before the phone could be completely activated. It's almost like the phone was in the same pre-activation limbo stage that frustrated many iPhone users waiting for activation the first weekend the device went on sale.

Gizmodo is reporting that both the original SIM cards as well as new SIM cards from AT&T won't work in iPhones that had been activated with the original SIM card, then unlocked from the network. That could present a huge problem for iPhone owners who thought they could get around the reactivation process by getting a new AT&T SIM card.
Did you hack your iPhone, and have you had similar problems after installing the latest update? Let us know.

We told ya. The best things in life are available only in Japan. This time it’s a Star Wars pod racer game for mobile phones. We can only imagine envious stares on the train while we blast other podders to smithereens. That's looking on the bright side because I think we're just as capable of driving commuters up the wall with our humming. According to Newlaunches.com, folks can either race against the computer or with other buddies.
It's finally here. Fuel cell technology in mobile devices, which has been talked about for the longest time, is finally coming to mobile devices. The first-generation 24/7 Power Pack charger from Medis Technologies promises to extend the talktime on handsets by up to 30 hours, 20 hours for smart phones or as much as 80 hours of playback for MP3 players such as the iPod. While we have yet to get our hands on one of these Power Packs for testing, we can already foresee how this will be useful for those who travel frequently or who just can't get enough yaktime out of their phones.
According to company representatives, the Power Pack activates once its tab is removed. After which, it can be used for up to three months.
It is currently available online at US$24.99 with refill packs going for US$19.99. Medis Technologies will also be offering an optional recycle program (in selected markets) to collect its used fuel cell packs back for refilling. The company has revealed that it plans to introduce a slimmer version of the Power Pack using solid fuel as well as a new model for power-intensive devices such as laptops.
