The truth about Blackberry?

I've heard a lot about Blackberry, but could not get clarity on the following issues:
  1. I argued that saving e-mail traffic through the Blackberry is due to the technology of push email. Say, you're running to the server, eating the money, and he hollowed to you if it is a letter and only in this case. For me, it sounds crazy. Indeed, in this case must be a constant connection to the server via GPRS. And traffic is still there. What happens in this case with a battery?
  2. Is there some sort of freebie when dealing with BES? Can be free traffic?
  3. What does the phrase "network coverage Blackberry"?
  4. I was told that unlike the iphone, devoured roaming$ 1500 for checking mail, Blackberry is free or nearly free. Is that so?
  5. The vaunted e-mail encryption at work with BES. This is the only channel encryption smartphone <-> BES, or something more?
  6. Savings when working with BES only achieved due to the compression? (such as Mozilla mail?)
  7. Does Blackberry something which is impossible on other smartphones?
  8. Is it true that BES should stand at the operator? Our operators should BES?
  9. For what it so love?

1. Yes, Push works when you register in Blackberry Service and ACC.configure. Usually the Blackberry Service agreement with the operator includes an item about the free service traffic, including a pounding from the server.
\r
2. Usually taken abon.fee and service traffic before it goes free
\r
3. Where local operators to give preferential access to Blackberry Services including Push email, free traffic, alerts and other services. Ie, the local network needs to negotiate with RIM.
\r
4. In those countries where the Blackberry Service and, accordingly, in the networks of those operators where there is a partnership
\r
5. Encryption of the packet data (not voice) during transmission, works in conjunction with Blackberry Service
\r
6. On account of the compression don't know, but the fact of the lack of periodic inspections (for push) effect. Perhaps the server optimizes the letters for the device (pinched picture, trim the extra headers...)
\r
7. Work with blackberry service, very good build quality, comfortable keyboard, business recognition (not pop), price level (to open it — and once everything is clear)
\r
8. Right for the services needs. At Beeline and MTS are.

I can only answer the first point. It's true. But only if you have official service. This automatically means that you're connected to the Internet constantly. The battery holds 4-5 days at ~15 min. calls and ~15 min of Internet a day. Can add the local browser is shit. And look sites with Opera Mini. Which, after Opera Mobile too. Phone Blackberry Bold 9700.

A bit of history, because then more difficult to explain. Since its inception (and it was the commercials in 2003 if I remember correctly), BlackBerry gave its users only two advantages, but these advantages were not at that time have competitors: (1) guaranteed message delivery time; (2) encryption of all traffic from the BES (which standards must stand inside the DMZ) to abrenskogo device. At that time nobody did that. TEXTS could goes days (72 hours waiting at SMSC — norm), mail or rush every 5 minutes or wait the sea weather. So BB was first evaluated by traders who need the speed of information transmission and secrecy. Well punters (especially lucky) in America — at the level of the Gods. And if they go with BB, this platform quickly became imageway for corporate klietnov. Just looking at BB, MS, swing and invented his PuchMail for WinMo, which actually started only in WinMo5.1 (it was not even in 2005 and later)
Now, in order asked questions.
1. They are not related things. "The kitten is warm because fluffy". No the kitten is warm and furry. You can, of course, to say that PushMail saves bandwidth due to the constant connection service, but do you imagine a "permanent connection" in the Internet? Static networks are not working. Nuger HeartBit — constant test pulses. MS, for example, simply refers to the ActiveSync server, an HTTP request with a very long response period. If on appears on the server it is passed to the callback. If the waiting time ends, the device raises the following session. And so all the time. You can see details at site MS Protocol description vSync. Details about BB I do not know, but it is unlikely there is something very different. And traffic compression is a simple algorithm ZIP hardware, there is also nothing original there. Another issue is that Paraty ZIP-th traffic then encryption is provided and this in itself adds a bit of traffic.
2. As said above — if BB have an agreement with the operator. Often this results in the fact that under the BB needs a separate tariff, to which you can connect only "when buying devaysa from the operator"... I'll need to check with your Opsosom.
3. I think the same as in paragraph 2
4. Roaming the Golden cow of all operators. Ten times to clarify this matter with the operator. Only if BB will pay one and another Opseu — then you roaming traffic will be free.
5. Yes, it is "vaunted encryption" in the best sense of the word. Quite strong thou a proprietary encryption algorithms BES <-> Smartphone. That is why our intelligence services so long to certify this system and certified in a very "neutered" version is when BES is the operator and between the operator and the email client — although the wind fistula (well, it's type, the client should care, but, again, all within the framework permitted by our special service protocols and systems).
6. Almost answered above. Compression, of course, but on top of it is the encryption, which let's not much, but traffic adds.
7. In Russia only "here, this a phone that no one else has!" In America is the corporate standard of all corporate standards. And we have MTS it is trying to peddle to simple users. Phone and phone. Operating system — its own app — very ogranichennogo list. With the Russian problem seemed to be gone, but... Full BlackBerry-Style devices of all manufacturers, from Nokia to HTC. PushMail ActiveSync on the Server (Exchange) similarly tight traffic, is able to ship the headers and not the entire mail, in the latest editions of WinMo 6.x is a very economical ate the battery, etc.
8. No, not true. As I said above, the BES needs to stand inside the DMZ, direct prirodnym to the mailer (Exchange, Lotus, etc.). Russian current implementation when the BES is at the operator's sake, more "big brother said to do so".
9. For what it's like in the USA, I wrote. I can say, for which he did not favor our corporator. (a) BES is the Opsosom to him as it is necessary to stretch to hemorrhoids. (b) All traffic from the BES is not going directly to Opseu, and swings through the Central server of BB USA. And who of our "petroleum" (for example) will want their traffic to swing through the USA, especially because the Protocol is proprietary, and parts of it no one knows except BB. "What if?" (it was still () but forgot... remember — write)

1. BIS is not available in my country so I use push mail through free service Shangmail. Any drawbacks compared to full BIS there is only delay in receiving an email in 1-5 minutes. Rates: in detailing Beeline marked only the points of receiving/sending letters — i.e., the interval of the copying is not happening. The battery requests charging every 4 days.
\r
2. On BES you can not say anything — probably depends on the agreement of the owner of the BES with the operator. In the BIS — and the monthly fee usually includes unlimited email and IM.
\r
9. For what it so love?
For the third BB and not nice I competitors. Ultimate intuitiveness, I guess. Moreover, both software and hardware.
Hoisted not one person on this wonderful device.

To use all the advantages of BB need to be connected to a paid service BES provider?
