Overall Blackberry device is not  different from other types of smartphones. The main thing that distinguishes the Blackberry is the Blackberry has its own identifier system and beyond mobile number itself.
Unlike cellular phones that communicate with a mobile number, Blackberry users also communicate with the PIN number each unit.
With the system, each user can communicate via internal Blackberry messenger is often called BBM (Blackberry Messenger), to exchange data (images, text, etc.), call (paging), exchanging calendar events (meetings, etc.).
Each unit is equipped with Blackberry 6 digit PIN (Personal Identification Number) that serves as an identifier for the unit to communicate with the system of Blackberry Internet Service (BIS) or BlackBerry Enterprise Service (BES). So, when we usually give to his mobile phone number, we need to give the PIN number to his Blackberry users to utilize the facilities provided Blackberry.
Blackberry PIN is we can not change or do we choose such mobile number, as it was already in the hardware (hardware) in units of the handset itself.
Registering Blackberry
To be able to use BBM, internet, etc.. Blackberry requires a special subscription fee beyond the usual telecommunications (phone / sms) called Blackberry Internet Service (BIS). Similar services commonly used by corporations called the Blackberry Enterprise Service (BES).
The main advantages that make Blackberry Blackberry is known its Push Mail technology. Although today the technology is already available on other mobile unit, known as the Blackberry smartphone ‘like’ always connected to the Internet.
If we need to first connect to the Internet to check email. With the Blackberry, the email sent by our colleagues will immediately be accepted at our Blackberry units.

Jakarta – BlackBerry handsets are usually sold quite expensive at the beginning of the marketing, including the Z10 is priced at about 700 USD. BlackBerry confirm they are not going to sell the new handset at a price too low. Why is that?
"You have to understand where you are playing (in the industry) and refused to talk about the segment, which you know there is no purpose and no value for shareholders," said CEO of BlackBerry, Thorsten Heins.
"You will not see us heading in the mobile segment of USD 50 or USD 60. This is not a BlackBerry," said the quoted from BGR, Monday (11/03/2013).
Z10 entry premium category which may not reach enough people. But Heins promised BlackBerry 10 handset at a price more affordable will be launched. Although it is not very cheap.
"You will see new products launched this year based BlackBerry 10, all have LTE capabilities, and the sale price toward the required people," he said.
Although sold at high prices, Heins claimed welcome in the developing markets of the Z10 is very good. As in India, there Heins claimed Z10 sold out.
"I was shocked when we launch it in India, how well sales of Z10 which is a high end device. I got an emergency call from the manager in India, said the stock runs out in two days. We strive add," continued the man’s German nationality.

BlackBerry officially released Z10 and Q10. Both handsets are using BlackBerry 10  system that presents a different experience compared to other platforms. Some reviews finals was aired, particularly for BlackBerry Z10 that has entered the testing and used in a long time by some media. Full touch screen handset is indeed the first to be marketed.

A technology that is created must have a function and a positive impact. Here are some the positive impact of the BlackBerry. BlackBerry has a high mobility . BlackBerry owners can send e-mail without having to visit the nearest Internet cafe.  BlackBerry owners can find news and important information anywhere. With the BlackBerry, users did not bother to look maps, because the BlackBerry can used as a navigator.

But blackberry service will give bad impact to our social culture. I say this not without cases. I often see the BlackBerry users bowed his head like a man who was a moment of silence. They were too busy interact with BlackBerry they are like no other people around them. In fact, often ignoring the social environment around them. I also often see when there is social interaction in the form of conversation, blackberry users are busy himself with his blackberry. It’s a bad thing, you try to appreciate the "friend" you, but just ignore of real friends in front of you. Come on guys, should not everyone is socially interact with the surrounding environment, not by what is in the cell?? Technological developments should be better utilized.

here is some negative impact on the user BlackBerry are follow as:

  1. BlackBerry can cause the wearer to be ANTI SOCIAL, because users are able to chat without having to meet people directly.
  2. Because have real time information its can loss concentration when driving the car or ride a motorcycle on way. Its can  cause of traffic accidents.
  3. BlackBerry may cause syndrome "crazy", because often look laugh alone without any apparent reason.
  4. Can break concentration while working.
  5. Use  BlackBerry service make a lot of spend  of money for buying the service package. 
  6. BlackBerry users can waste time with the BlackBerry Messenger feature.
