    Last batch of prototypes, this time one 5810 and one 5820. I will be focusing on the 5810 development process as that was the first one to come. All this information was gathered from the FCC website. You can check it out here: https://fccid.io/L6AR1900G-1-4
    Alright, a little background information first. After the huge success of the previous pager series and the rise of the GPRS technology, RIM decided to expand into that market. Their pager devices were limited to Canada and the U.S. because the network system they used. RIM was ready to go international. The first documents of the project were submitted to the FCC on 24 January 2001. The code name was R1900G-1-4, official name Blackberry Wireless Handheld.

    The design was a direct copy of the 975 model. In this first prototype photo the device has the exact same housing as the pager models. Later on the Blackberry logo was moved above the LCD and the carrier logo was placed below the keyboard.
    Documents state the testing of the prototype was done by Ultratech engineering labs in 22-25 March 2001.
    The User Manual is dated 18 January 2001 and complies with OS version 2.0.13
    If you read that manual, there is no mention of the Phone capability of the device..at all! It is only mentioned in the safety section that if you are using a peacemaker and the device has a voice option, always use the headset opposite of your peacemaker to prevent interference. Now, in all the articles I read about the 5810, everyone said that RIM rushed with the release of this device so much that they forgot to implement microphone and speaker inside. That is not the case. In the first user manual there is no mention on any phone call option. The primary use of the device is stated to be e-mail and personal digital assistant. When the FCC asked for a clarification on what exactly is this thing, the response was: " The Blackberry handheld is primarily a data device with voice capability via the headset as an added feature". It was not intended to be a phone. RIM was using the GSM network for transmitting data, gave it a audio port just as a side feature.
    There is a lot of documentation regarding the radiation levels emitted by the device, with the usual demand that it should only be carried on the belt clip, not in the pocket.
    On 27 July 2001 RIM released new test results because they had to make a small change in the antenna design to accommodate a new battery and LCD ( they switched from Toshiba batteries to GS Melcotec and from Epson LCD to Samsung LCD).
    On 26 September 2001 RIM sent a letter announcing further changes to the antenna and radio to reduce the radiation levels. New test results submitted.
    The device was finally released in March 2002 in North America, with the 5820 following in September for the European market.
    The code names indicated the network frequency the device was working on:
    5810 R1900G-1-4 on 1900Mhz
    5820 R900/.1800G-2/1-4 on 900 and 1800Mhz.

    The model is also known as the R900.

    The 5810 was the first device to have a Java-based OS, and it remained so until BB10 replaced it 11 years later.

    In October 2004 RIM released the 5790. It was a basically a RIM 957 Mobitex pager but with a Java- based OS and 16MB Memory.

    Now let's have a look at these prototypes.

    Compared to the official 5820, they are pretty much identical, the only difference being the white SIM unlock clip on the 5820,the stickers at the back and the ALT key (the final release had ALT printed on the key instead of just a plain orange key).
    Notice the PIN numbers:

    These have what used to be called a 'golden PIN'. I read stories about Arabian princes offering thousands of dollars for a BlackBerry with such a sequence of numbers. I guess it was like massive companies wanting those special phone numbers to spell out their name. It was important to them to have a fancy PIN. I actually had a person from Dubai last year asking me to find him a BlackBerry with a 'golden PIN'.

    Looks like these devices belonged to developers. Both have games and small programs on them. I have handled hundreds of 5820 over the years but this is the first time I see any app or game other than the official OS on these! Not sure if there was no interest from developers in this device or maybe the OS was just self sufficient? It's a shame I can't extract these games out and share them with other people.
    The OS installed seems to be a Beta release.

    Now let's have a look inside the device. I will compare the 5820 prototype with an official one as I don't have any other 5810 at hand. The prototype is the one on the left.

    On close inspection, there are differences in the PCB,especially around the antenna ribbon. This confirms what RIM stated in the letters to the FCC. The wheel PCB is also different.

    Not much difference at the front. Notice the different screen.

    Let's have a look at the back of the LCD

    Curious. RIM told the FCC they changed from Epson screens to Samsung ones but the official release has just a modified Epson LCD installed.

    Not much else to say about these. Check my video bellow if you want to see more of these devices, I take a look at those games as well:


    I also have a very early RIM 957 pager here, runs OS 2.6.0.36 and has only 5MB memory.

    I also have this sealed copy of RIM Developer program.

    I won't open it but if you want the SDK, I found it a few months ago online and made a post about it here:https://forums.crackberry.com/older-.../#post13341650

    GAMES... so many here always say that they don't need games or social media, but BlackBerry seems to have always had games and BBM was a very early social media platform.

    Shame there aren't any more of them, such a large monochrome LCD could be put to good use!
