If you happen to find yourself in a rush to get out of the door as soon as possible and want to make sure you have a full battery on hand with your iPhone 4, you might want to charge it via the included wall charger. Apparently it takes an average of 23 percent longer to charge it through a USB port on a computer or some sort as opposed to using a wall charger. Click here more news

New iPhone system, with multi-tasking, unveiled

Cupertino, California (Wired) -- Apple unveiled details of its next-generation iPhone operating system Thursday in a press event at the company's headquarters here.

The new operating system, iPhone OS 4, will be released to developers this week and to consumers this summer. It will give developers access to calendar, photo library, still image and video data, and includes features aimed at helping apps run faster.

As expected, the new OS will support multitasking of apps.

"We weren't the first to this party but we're going to be the best, just like cut and paste," said Apple CEO Steve Jobs, alluding to the fact that cut-and-paste hadn't been available until a year after the first iPhone launched.

"It's really easy to implement multitasking in a way that drains battery life. If you don't do it just right your phone's going to feel sluggish and your battery life is going to go way down. We've figured out how to implement multitasking of third-party apps and avoid those things."

With the new OS, users will be able to press the home button twice to see a menu of all the currently active apps, which appears as a bar along the bottom of the screen. Tapping one of the apps takes you directly into that app. Apps can remain running in the background.

Apple demonstrated how you can keep listening to music in Pandora while doing other things on the phone, and how the phone could deliver push notifications to alert users to an incoming Skype call.

"It was really simple to implement. Just a dozen lines of code," said Skype's head of product development David Ponsford.

To address privacy concerns, the OS will also let you know (via a notification on the app's icon) when an app running in the background has requested your location from the device's GPS.

The announcement comes less than a week after Apple's launch of its tablet computer, the iPad. Jobs said the company had sold 450,000 iPads to date, and that users have downloaded more than 1 million iPad applications and over 650,000 digital books from the iBooks store.

Jobs also added that the company has sold more than 50 million iPhones and 35 million iPod Touches.

The iPhone, iPod Touch, and iPad all run iPhone OS 3.0. The operating system is based on an OS X core, but with a touch-centric interface and optimizations aimed at increasing screen responsiveness and maximizing battery life.

The current iPhone OS has been widely criticized for its lack of support for full multitasking: It only allows a few core apps, such as iPod and Mail, to run in the background while another app is active. The OS also restricts add-on software to apps available through Apple's App Store.

The App Store currently contains 185,000 apps, Jobs said, adding than users have downloaded more than 4 billion apps from it to date. About 3,500 of those apps are optimized for the iPad.

The new OS also gives users the ability to group apps in folders, instead of just laying them out on the home screens.

Other features planned for iPhone OS 4 include a 5x digital zoom feature in the camera, and the ability to tap to focus in video. (Tap to focus was already available for still images in iPhone OS 3.)

New iPhone app translates baby's cries

Does he want a nap? Maybe a snack? Translator can help you figure it out

Next time your baby cries, you might want to hold the little one up to your iPhone. A new app could translate those yells into adult-speak, telling you whether it's a cry for food or perhaps a nap.

After 10 seconds of crying, the Cry Translator (patented by Biloop Technologic, S.L.) will light up one of five icons to indicate, the company claims, whether your baby is hungry, tired, bored, sleepy, stressed, or in some kind of discomfort.

While you might think the cry decoder is as valid as having a conversation with your dog or cat, some research suggests there is meaning behind those wails.

Other more recent research has shown the cries of newborns already bear the mark of the language their parents speak. For instance, one study showed French newborns cry with rising melody patterns, slowly increasing in pitch from the beginning to the end, while German newborns have falling melody patterns, both of which are consistent with their prospective languages. That suggests infants are already picking up bits of language in the womb.

And while newborns may not have language for some time, pediatricians have known they cry to communicate.

"Babies do cry; it's their main form of communication," said pediatrician Jamie A. Freishtat, adding that over time parents tend to figure out what certain cries mean. "I know that anecdotally a lot of parents, after time, say, 'Ah she must be wet,' by a certain cry. I think pain [is something] parents tend to pick up on."

That "I'm in pain" cry could be higher pitched or more shrill, said Freishtat, who is also a spokesperson for the American Academy of Pediatrics (AAP).

Even so, all babies sound different, just like adults. "I'm not sure if you had ten babies and they were all hungry if you would get the same cry from each baby," Freishtat told LiveScience.

The Web site set up for the new baby-cry app acknowledges the variability of cries, explaining that rather than tone or pitch, the technology relies on some kind of pattern in the cries.

The company cautions, however, that the technology is meant to help parents and caregivers understand what their infant is trying to communicate and is not a stand-in for a medical doctor.

Freishtat echoed this caution: "Regardless of how a parent is trying to interpret his or her baby's cry, if a baby is ever crying inconsolably (won't stop regardless of interventions, such as offering a feed, changing a diaper, holding the baby, etc.) then it is very important to contact or go to the doctor immediately because that can mean there is something more serious going on."
