upgrade

Samsung, the maker of past iPhone processors, has revealed its latest ARM chip. Clocking at an outrageous 1 GHz, this chip only consumes 640mW of power.

The new ARM, nicknamed Hummingbird, uses the same Cortex-A8 architecture featured in the iPhone 3GS. The new chip includes Neon, which speeds up video and audio tasks.

The Hummingbird is the first ARM-based processor design to be built by Samsung using a 45 nanometer assembly process. This keeps energy efficiency at a maximum and lowers the heat emissions of the chip. The Hummingbird only requires one volt of power to operate.

Only a week after the previous release, Apple has made iPhone OS 3.0 beta 5 available. Several new tweaks and features are apparent as the final release date for the new operating system approaches. Apple has also announced that all AppStore applications submitted for approval must be OS 3.0 compatible going forward.

First of all, leaked screenshots have confirmed rumors of a built-in digital compass (magnetometer). Along with the GPS and accelerometer, the compass could improve navigation and make a variety of "augmented reality" applications possible by overlaying graphics on top of live video.

Jibbler? The name may be awkward, however the code buried within iPhone OS 3.0 it refers to could make the iPhone much more talkative. Jibbler works with the SpringBoard and Spotlight in iPhone OS 3.0 to recognize and synthesize speech.

With improved processing power, it's possible the next iPhone could be controlled by the user's voice. In addition, the iPhone could read off contact names, calendar entries, or song titles on demand. A new Voice Services class has been discovered which may mean that Jibbler will be available to developers in Apple's Software Development Kit (SDK).

With the initial excitement of Apple's iPhone 3.0 preview already passed, users of the iPhone OS 3.0 Beta have been finding several new features that appear to be in the works for a next generation device. One such feature is video recording, which reports have indicated would come along with an upgraded camera and possibly a multi-core GPU (graphics processing unit).

Backing up the claim are screenshots from the MobileMe upload screen in iPhone OS 3.0 that say "Publish Video" at the top of the app. Of course, a better camera would mean higher-resolution still photos, too. Other features that look interesting have also appeared in leaked screenshots of iPhone OS 3.0 Beta.

Apple held their widely anticipated iPhone OS 3.0 preview today in Cupertino, California. There are 100 new features on the way in the new operating system, which will ship this summer and cost nothing for existing iPhone users (iPod Touch users will pay $9.95 for the update).

Scott Forstall, the head of iPhone software development, described iPhone OS 3.0 as "a major update to the operating system." Here's a list of the features announced at the event:

Billed as an advance preview, Apple's March 17th event to discuss the iPhone OS 3.0 software and SDK is generating quite a buzz. Most speculation revolving around the event has rehashed old, tired rumors about features that have failed to materialize on the iPhone, however there are some new developments.

Two of the most interesting new firmware 3.0 predictions are reports of a revised SpringBoard and possible iPhone support for magnetometers. A update to the SpringBoard could include features to help organize multiple applications into folders or categories on the home screen. Magnetometer? Think digital compass, à la Android G1.

AT&T may begin offering its customers discounts on new phones if they trade in an older model. Rumors of a possible June launch to the program have iPhone enthusiasts buzzing about the implications. The possibility of a next-generation iPhone launch to coincide with a trade-in policy means users returning their old phone could get up to $200 back if the device is in good shape.

Preliminary rules indicate the phone being returned can't be more than two years old. Depending on what shape the phone is in and the model, trade-ins will net the customer $50 to $200 bucks off their purchase of a new phone.
