All About iPhone Serial Number.

Your iPhone serial number provides interesting information about the device. Serial number tells you about the device manufacturing date, warranty and even some time easy to recognize a fake iPhone from the serial number.

Here is the step to describe how to locate your iPhone serial number. It is good to note down serial number to refer in future.

iPhone serial numbers come in the form WW011XXXYYZ which can be read as follows.

WW = Factory and machine ID
0 = Year manufactured (simplified to final digit, 2011 is 1)
11 = Week of production
XXX = Unique identifier
YYZ = Color, model and size

While the last 3 digits of iPhone serial number can be read as following:

VR0 (iPhone 2G Silver 4GB)
WH8 (iPhone 2G Silver 8GB)
0KH (iPhone 2G Silver 16GB)
Y7H (iPhone 3G Black 8GB)

How to check iPhone Fake or Not

Do you ever think that you brought a fake phone? Or did you see a cheap deal for iPhone and you suspect that it is a imitation of iPhone? You can identify a genuine iPhone from a fake iPhone. Please follow these guides to make sure you are buying a real iPhone.

Touch Screen: This is one of the easiest way to identify a fake iPhone. The real iPhone comes with a glass touch panel, where the fake one may be plastic. If you apply slight pressure on the iPhone screen and if you can see some color changes on that spot while pressing, that is fake iPhone. The second thing is the sensitivity of the touch panel. The sensitivity of a fake iPhone screen will be lower. It may take mare attempts or pressure to react with your finger movements. If your iPhone reacts with a Metal or Plastic styluses, it is not real. The real iPhone will not work with Metal or Plastic styluses.

Memory Space and Battery: The real iPhone has no memory space or card slots. It comes with one SIM card slot on top, and the batteries are not replaceable by the user, means the battery is not easy to take of from the iPhone with a sliding door. If any iPhone coming with these features, they are not real iPhones.

Touch Screen Size: If you get a chance to open and see the iPhone before you buy, please measure the screen size with a ruler. It should measure exactly 3.5 inches (8.9 centimeters) for iPhone4. If you see a lower or higher size, that is the bad apple.

iPhone Back Panel: Fake iPhones are coming with plastic back cover. The original iPhone coming with Metal panel and Glass back panel in iPhone4 models. The back of your iPhone should always list a model number, and IC ID, and the phrase “Designed by Apple in California. Assembled in China.” If you have an iPhone with any other color except black or white, it is not real one.

iPhone Icons: When you turn on iPhone, genuine iPhone will display four rows of icons with a black background. So many fake iPhones are coming with a clouded back ground.

Serial Numbers: You can get the iPhone serial number here. This post tells you all about iPhone serial number. If you see any change in the format code, be careful. Also you can check your iPhone warranty in apple website, the link also provided here. If you enter the serial number and it’s not recognized by the site, you can assume that you got a bad apple.

Menus and Apps: There should have some changes in menus in actual iPhone and fake one. You can’t see any busy hour glass or any delay while opening a new genuine iPhone. If you see these busy icon or unusual deal to open an apps, that is from a fake iPhone.

A couple of points to take care:

• When you turn on the fake iPhone, it will not give you a slide to unlock option.
• The iPhone menus may be different the icons are almost similar to original one.
• The music player and video players appearance may be differ than the original one.
• Fake one may not have auto turn off screen while calling.
• The auto rotate feature may not come with fake one.

Always try to buy from Apple store or an authorized retailer, will be a good choice to get a genuine iPhone.

Scientists plan to sail on lakes of Saturn's largest moon Titan

After the successful landing of 'Curiosity' rover on Mars, scientists now plan to navigate the seas of Saturn's largest moon, Titan.

According to scientists presenting their proposals at the European Planetary Science Congress, this outlandish scenario could soon become a reality.

The new project, called the Titan Lake In-situ Sampling Propelled Explorer, proposes a boat-probe, propelled by wheels, paddles or screws.

The probe would land in the middle of Ligeia Mare (the biggest lake, near Titan's north pole), then set sail for the coast, taking scientific measurements along the way. The mission would last around six months to a year.

"The main innovation in TALISE is the propulsion system," Igone Urdampilleta, a member of the TALISE team said.

"This allows the probe to move, under control, from the landing site in the lake, to the closest shore. The displacement capability would achieve the obtaining of liquid and solid samples from several scientific interesting locations on Titan's surface such as the landing place, along the route towards the shore and finally at the shoreline," Urdampilleta said in a statement.

The TALISE concept is being developed as a partnership between SENER, a private engineering and technology group and the Centro de Astrobiologia in Madrid, Spain.

This mission concept is the result of a 'phase 0' study. In the following phases the feasibility study and a preliminary mission architecture would be realised to consolidate a possible technical proposal for future space science mission call.

Titan is one of the most Earth-like bodies in the Solar System. With a thick atmosphere, a diameter between that of Earth and the planet Mercury, and a network of seas, lakes and rivers, it is in many respects more like a planet than a moon like Earth's.

The satellite's atmosphere is made up largely of nitrogen (like Earth's), is rich in organic compounds and hydrogen cyanide, which may have played a role in the emergence of life on Earth.

The Cassini-Huygens mission, which studied Titan extensively in the 2000s, confirmed that lakes, seas and rivers of liquid hydrocarbons (similar to household gas) exist, covering much of the satellite's northern hemisphere.

Although it eventually landed on solid ground, the Hugyens lander was designed to be able to float for a short period.

US drones will soon be overtaken by new wave of robots

The US military's current fleet of drones will soon be overtaken by a new wave of robots that will be faster, stealthier and smarter -- operating virtually without human intervention, experts say September 26, 2012. The Pentagon is investing heavily in 'autonomy' for robotic weapons, with researchers anticipating squadrons of drones in the air, land or sea that would work in tandem with manned machines -- often with a minimum of supervision.

WASHINGTON: The US military's current fleet of drones will soon be overtaken by a new wave of robots that will be faster, stealthier and smarter -- operating virtually without human intervention, experts say.

The Pentagon is investing heavily in "autonomy" for robotic weapons, with researchers anticipating squadrons of drones in the air, land or sea that would work in tandem with manned machines -- often with a minimum of supervision.

"Before they were blind, deaf and dumb. Now we're beginning to make them to see, hear and sense," Mark Maybury, chief scientist for the US Air Force, told AFP.

Unmanned aircraft are now overseen by "pilots" on the ground but as the drones become more sophisticated, the role of remote operators will be more hands-off.

Instead of being "in the loop," humans will be "on the loop," said Maybury, explaining that operators will be able to "dial in" when needed to give a drone direction for a specific task.

"We're moving into more and more autonomous systems. That's an evolutionary arc," said Peter Singer, an expert on robotic weapons and author of "Wired for War."

"So the role moves from being sort of the operator from afar, to more like the supervisor or manager, and a manager giving more and more of a leash, more and more independence," he said.

Despite the dramatic advances in technology, the American military insists humans will remain in control when it comes to using lethal force.

But the next generation of increasingly capable drones will stretch man's capacity to control robots in battle, generating unprecedented moral and legal quandaries.

"These (technological) responses that are driven by science, politics and battlefield necessity get you into areas where the lawyers just aren't ready for it yet," Singer told AFP.

Over the next decade, changes in computing power will enable teams of hi-tech drones to operate virtually on their own, or as "robotic wingmen" to piloted aircraft, said Werner Dahm, the Air Force's former top scientist.

At a testing range in the Arizona desert, Apache helicopters are flying together with unmanned choppers in experiments the Pentagon believes will serve as an eventual model for future warfare.

"We're not far away from having a single piloted Apache or other helicopter system and a larger number of unmanned systems that fly with that," said Dahm, a professor of mechanical and aerospace engineering at Arizona State University.

"These require very high levels of machine reasoning. We're much closer to that than most people realize," Dahm told AFP.

The new technology has turned the US Air Force's doctrine upside down. For decades, the military trained pilots to face an enemy "alone and unafraid," flying deep into hostile territory to strike at a target and then return home.

Now the Air Force is planning for scenarios in which different tasks would be divided up among manned and unmanned "systems," with drones jamming enemy air defenses, tracking targets and assessing bomb damage, while piloted warplanes oversee the launching of bombs and missiles.

Nokia launches City Lens Point application

NEW DELHI: Finnish handset maker Nokia launched a new app City Lens Point which allows users to search places as well as get directions and reviews to popular restaurants and shops.

The application has been launched for its Lumia series of phones and other smartphones.

"Using the augmented reality app, when the user holds their device up, the City Lens overlays information about restaurants, shops, hotels and other popular destinations nearby," Nokia India Director Sales V Ramnath told reporters here.

It also allows one to make reservations or navigate to the location via turn by turn walking map, he added.

"This application from Nokia's Location service bouquet allows users to sense the world around and discover places by simply holding up their smartphone instead of having to perform web searches. It's simple and it's spontaneous," Ramnath said.

The free application is available for Lumia 800, 710 and 900, while it is also available for Nokia's other smartphones like Nokia 700, 701 and N8.

India’s heaviest satellite GSAT-10 launched

GSAT-10, the country's newest and heaviest satellite, was launched in the wee hours of Saturday from the Kourou launchpad in French Guiana in South America. It will directly boost telecommunications and direct-to-home broadcasting among others.

The satellite, 9th in ISRO's present fleet, will be operational in November and add 30 transponders to the domestic INSAT system, Indian Space Research Organisation (ISRO) said soon after the launch.

The ISRO launched the 3.4-tonne spacecraft on the European Ariane 5 rocket as the agency cannot currently launch satellites of such mass on its own vehicles. The satellite and the launch fee cost the agency Rs. 750 crore.

The ISRO called its 101st mission "a grand success," adding that the satellite was in good health.

ISRO's Chairman and Secretary, Department of Space, Dr. K. Radhakrishnan, and senior scientists have been at the Master Control Facility, Hassan (some 80 km from Bangalore) since Friday evening. It is also the first time that the Chairman was not present at the launch site.

Other Indian scientists present at Kourou included Director, Satellite communications, Prahlad Rao and Project Director T.K.Anuradha.

What the satellite brings

It carries 30 communication transponders - 12 in Ku-band, 12 in C-band and six in extended C-band. The ISRO is currently leasing 95 foreign transpondes to meet domestic demand. The INSAT/GSAT system has 168 transponders.

The Ku band is vital for seven DTH TV operators and thousands of VSAT operators who provide phone and Internet broadband connections. Public and private telephone and television providers also use the C band.

GSAT-10 also has the second GAGAN payload which augments or finetunes the US GPS signals into far more accurate readings. GAGAN, a venture of the Department of Sapce and Airports authority of India, is primarily meant to benefit airlines and their aircraft flying into and out of India. GSAT-8, launched in May 2008, carried the first GAGAN payload.

The flight at 2.58 a.m. IST was preceded by a countdown lasting for 11.5 hours. By 3.19 a.m. it was visible to scientists waiting to capture its signals at Hassan.

"MCF took over command and control of the satellite immediately after the injection. Preliminary health checks on various subsystems such as power, thermal, command, sensors, control etc., have been performed and all parameters have been found to be satisfactory. The satellite has been oriented towards Earth and the Sun using the onboard propulsion systems," the agency said.

In the coming days, MCF scientists will perform routine manoeuvres to "raise" the elliptical orbit into a circular orbit with 24-hour rotation around the Earth and fixed at 83 degrees East slot over the Indian region at 36,000 km above ground. They will do this by firing the apogee motors on board the satellite in three steps.

Later the antenna, solar panels and other instruments will be deployed and switched on.

Built for 15 years, GSAT 10 will be co-located with InSAT-4A and GSAT-12.
