How to Check – Phone is Original or Fake ?

As replica phone are present in the market that looks similar to the original phone, to check whether your phone is original or fake there are two ways of checking it. These methods will help you a lot while buying a used cell phone.

First Check the following Features :

• Be careful about the spellings For example, Soniericsson, Nokla and Samsvng
• Warranties:  Always insist on 12 months warranty certificate from the handset manufacturers; Never an oral agreement with the seller. Fake phones come with a shorter warranty periods since counterfeiters cannot guarantee it will last so long
• Check for performance of the handset: Some people carry their phones home without testing it first. Some dealers encourage this, knowing the handset is fake. As you check it out, you may notice some points of low performance such as memory which is smaller or poor quality photos.
• Appearances: like dull colors , Fake logos,built quality difference in weight, screen size, location of buttons and battery, quality of printing and paint finish, added or missing functions, quality control stickers and holograms and an overall lack of quality.

• The other method is checking Phones quality through 15 digit IMEI code :
• Dial *#06#

IMEI stands for International Mobile Equipment Identity. It is a 15-digit number and may be found in the packet of the mobile phone. It may also be found by removing the back cover and it may be placed on the battery sticker.

The number might be as below: 

3 6 9 3 9 5 0 1 2 3 5 5 6 7 8

Now look at the 7th and 8th digit. These two digits will ensure your phone’s quality!

• If the seventh and eighth digits are 00 this indicates your cell phone is manufactured in Original Factory which ensures the best quality.

• If the seventh and eighth digits are 01 or 10 this indicates your cell phone is manufactured in Finland which is high quality.

• If the seventh and eighth digits are 13 this indicates your cell phone is assembled in Azerbaijan which is too bad. And it is also dangerous for health!

• If the seventh and eighth digits are 02 or 20 this indicates your cell phone is assembled in Emirates which is very poor quality. (NB: Some Indian sets have this number)

• If the seventh and eighth digits are either 03/30 04/40, this indicates your phone is made in China but its quality is good. But not good either as 00, 01 or 10.

• If the seventh and eighth digits are 05 or 50 this indicates your cell phone is manufactured either in Brazil or USA or Finland.

• If the seventh and eighth digits are 06 or 60 this indicates your cell phone is manufactured either in Hong Kong, or China or Mexico.

• If the seventh and eighth digits are 08 or 80 this indicates your cell phone is manufactured in Germany which is fair quality.

This will help you to pick the good one. Try it. But, remember, these tips may not work with the Sony Erickson Mobile Phone.
Though the above information has been collected from very reliable sources, 1 or 2 of them may slightly vary.

Moving Paragraphs using shortcut key in MS Word

Some times after writing a paragraph, we want to move the paragraphs up or down.  MS word provides a easy shortcut to move paragraph up or down.

Shortcut to move paragraph up or down:
Place the cursor to paragraph which you need to move.
Press [Alt]+[Shift] and up arrow to swap the paragraph which is placed above the paragraph you want to move.
Press [Alt]+[Shift] and down arrow to swap the paragraph with below paragraph.

These shortcuts are compatible with Word XP, 2003, 2007 and 2010.

6. Type netsh int tcp set global autotuninglevel=normal and Enter
7. Type netsh int tcp set global congestionprovider=ctcp and Enter
8. The last one is same as the first one, Type netsh int tcp show global and Enter agan!
9. Now, you can see is it work or not by surfing on the internet, ENJOY!

P.S: This simple don't requires any RESTART!

Hidden cameras, spy cameras or video cameras

Cameras has become the new trend of the modern world. In recent times most of the organizations as well as individual personals use  various type of cameras to make their tasks more easy. In this post today i am going to discuss the importance and effects of using   hidden cameras, spy cameras or video cameras.

Hidden cameras

These type of cameras are used to in the hope of collecting secret information about some personal or organisation . The advantage of using these kind of cameras are you can use them without directly seen. These are mostly placed in ones shirt, ring, watch, specs . Latest method is to use them as eye lenses.

video cameras

video cameras are the most common thing to all of you as far as every act is concerned. This is the first invented camera and today this type is widely used in cinema. Video cameras has gone to a huge standers that today a small camera is able to record huge data can be stored safley

Spy cameras

The spy camera is one of today's most common equipment . Spy cameras can be found in  both wired and wireless. Spy  cameras are the most difficult to install but they provide  the best solution for long term use. The wired spy cameras  can be used in many official and household items . The spy cameras  provide the must needed portability and ease of use even though wireless cameras are often powered by battery life unless a mains supply can be used.

JAVA TECHNOLOGY

JAVA being the most famous computer language according to TIOBE website (refference http://www.tiobe.com/index.php/content/paperinfo/tpci/index.html) has favoured millions of  of programmers around the globe. Reason for huge publicity for this language overtaking well known languages such as C#, C++ is that not only being a OOP(Object Oriented Programming ) language but also provides great facilities to programmers. The platformes SE,ME,EE  provides programmers to make their choise.

History of JAVA


In 1991, a group of Sun Microsystems engineers led by James Gosling decided to
develop a language for consumer devices (cable boxes, etc.). They wanted the
language to be small and use efficient code since these devices do not have
powerful CPUs. They also wanted the language to be hardware independent since
different manufacturers would use different CPUs. The project was code-named
Green.
These conditions led them to decide to compile the code to an intermediate
machine-like code for an imaginary CPU called a virtual machine. (Actually, there
is a real CPU that implements this virtual CPU now.) This intermediate code
(called bytecode) is completely hardware independent. Programs are run by an
interpreter that converts the bytecode to the appropriate native machine code.
Thus, once the interpreter has been ported to a computer, it can run any
bytecoded program.
Sun uses UNIX for their computers, so the developers based their new language
on C++. They picked C++ and not C because they wanted the language to be
object-oriented. The original name of the language was Oak. However, they soon
discovered that there was already a programming language called Oak, so they
changed the name to Java.
The Green project had a lot of trouble getting others interested in Java for smart
devices. It was not until they decided to shift gears and market Java as a language
for web applications that interest in Java took off. Many of the advantages that
Java has for smart devices are even bigger advantages on the web.
Currently, there are two versions of Java. The original version of Java is 1.0. At
the moment (Nov. 1997), most browsers only support this version. The newer
version is 1.1 (in addition 1.2 is in beta). Only MS Internet Explorer 4.0 and Sun's
HotJava browsers currently support it. The biggest differences in the two versions
are in the massive Java class libraries. Unfortunately, Java 1.1 applets will not run
on web browsers that do not support 1.1. (However, it is still possible to create
1.0 applets with Java 1.1 development systems.)

About Apple iPad 3

Apple’s iPad 3 will use the quadcore Apple A6 chipset and offer a combination GSM/CDMA/LTE radio, according to a new leak from a source claiming to have access to the next-gen tablet itself. Details of the third-generation iOS slate were culled via debutting tool iBoot, BGR‘s source suggests, with the same J1 and J2 model references as spotted in an iOS beta, now believed to refer to the WiFi-only and WiFi + 3G/4G variants.

The Apple A6 processor, meanwhile, has the model number S5L8945X. Details on the A6 have not been released by Apple, but the chipset is expected to have not only four cores but upgraded graphics capabilities driving a “Retina Display” panel running at 2048 x 1536 resolution. Despite their legal differences currently clogging up courts worldwide, Samsung is believed to be manufacturing the A6 for Apple

As for connectivity, LTE has been well-rumored and would certainly fit in with Verizon and AT&T in the US. The combination modem would also make sense for the multiple countries without 4G LTE networks, presumably offering HSPA+ connectivity as well.

Of course, this sort of screenshot would be relatively straightforward to fake, and so – as with most Apple rumors – we’ll take them with a heaped serving spoon of salt. It’s unclear whether the tablet will be the iPad 3 or, as other rumors have indicated, that Apple will  push our an iPad 2s first as a more incremental update.
