Unlocking blackberry 8520

I would like to unlock my blackberry 8520 cause i want  to go to a different network. Apparently all 10 attempts have been used, is anything i can do now? Thank you

I have never directly faced your situation, so have no experience to guide me. I cannot predict what path would be faster. Well, actually, the fastest path is to abandon this BB and buy a new one from the carrier you wish to operate on. After all, shifting a BB to another carrier is challenging even beyond just the act of unlocking...if the new carrier does not directly support your specific BB model number, getting full BB services to function on it can be even more challenging (the carriers typically only send the necessary Service Books down to the BB model numbers that they directly support, so you must work some difficult magic to get a non-supported BB model to work on that other network). Plus, some carriers may well forbid your BB model from their network...it's their network, after all so they can say that.
I've never used the trade up program either, so I have no experience about that.
All in all, I can't guide you one way or another as my decision criteria may be different from yours. I think I've provided you with all of the various pros and cons that I am aware of...but the decision is yours.
Good luck!

  • Question about the BlackBerry 8520 Unlocked

    Hi all,
    I've a question about the BlackBerry 8520.
    I saw it's being sold as unlocked and I'm wondering if once I buy it I need to have a particular carrier plan to use it or if I can simply use my pay as you go At&t plan.
    So far I didn't buy any smartphone, iPhone, Android and so on because I don't want to be forced to add a monthly plan, that by the way usually is not cheap here in LA (around $70-$90 per month). But I'd like to have a BlackBerry as I guess I could use, even without the usual carrier plans, most of its features (but please correct me if I'm wrong).
    So, basically the question is: would it make sense to buy the 8520 even with my basic "pay as you go" plan?
    Thanks for any info.

    Haha... so, probably whatever I write in this forum it doesn't matter. That's nice, it could be the perfect place where I can just rant or write anything that comes to my mind. Cool, I'll keep you guys updated. Stay tuned, some good rant coming soon!

  • Opening pdf file in Blackberry 8520 curve

    I am unable to open pdf file in my blackberry 8520 curve. Can anyone help me in this regards. The mobile does't have any pdf reader pre installed. Do we need to install software, if so please send me the link to download or the software itself.
    Thanks

    PDF files can be easily viewed as an attachment to an email.
    If you are wanting to view a PDF file downloaded to your Media Card, you will need a third party application, such as PDFtoGO, BeamReader or Repligo. Google will find any of those three for you.
    Good luck.

  • Blackberry 8520 Media card

    Hello, i cant recognize in my blackberry 8520 any media card. Can any one help me?
    Thanks

    What kind of media card are you using, what size, and what type?
    What is your Operating System loaded to your device? Look at Options > > Device > About, third line down beginning with a "v.5.0.x.xxx", What is yours?

  • Blackberry 8520 does not start up

    HI,
      I have just bought a Blackberry 8520.
    It has been working fine till today suddenly a white screen came on with a small clock icon in the centre.
    The phone does not switch on. I have tired taking the batter off, sim and the memory card but nothing helps.
    If anyone know how to rectify this problem I would really apprecaite it.
    P.S I use MAC

    You'll need to get access to a PC.
    If your BlackBerry stays powered off with a black screen, follow the instructions below. The only indication of life might be the blinking red LED light in the top corner. Nothing seems to wake it up and Desktop Manager doesn't recognize any device is connected.
    1) Make sure you have Blackberry Desktop Manager installed.
    http://na.blackberry.com/eng/services/desktop/
    2) On your PC, go to Start > Run and copy and paste the following line exactly (meaning with the quotation marks):
    "c:\program files\common files\research in motion\apploader\loader.exe" /nojvm
    3) The Application Loader Wizard will appear -- click "Next."
    4) In the "Connection:" drop-down menu, you should see "USB-PIN: UNKNOWN". Click the "Next" button.
    5) You should then see a list of applications ready to be installed for your Blackberry. Hit Next and Finish and you are well on your way to getting your Blackberry back to life. Congrats! Just don't disconnect anything and let the lengthy process finish completely.
    NOTE: If you do not see a list of applications mentioned in step 5 and instead see the message "The Blackberry Desktop Software does not have Blackberry Device Software for the device that you have connected to the computer. Contact your wireless service provider or system administrator," then you must download Blackberry's Operating System for your carrier and device.
    http://www.blackberryfaq.com/index.php/BlackBerry_​Operating_System_Downloads
    Just select the appropriate carrier and network type, select your Blackberry model from the list and download the latest version. Install this download and follow the above steps again and you should be on the right path.

  • Blackberry 8520 - Generic Data Plan

    I just recently purchase a 3G generic data plan for my blackberry 8520 under a mistake. I understand that this plan is not suitable for bbm or any other RIM services, however I expected that I could still use third-party application like Whatsapp, Opera Browser, etc, based on facts from (http://www.ehow.com/how_7664566_use-blackberry-generic-data-plan.html, http://www.blackberryfaq.com/index.php/How_to_use_BlackBerry_on_Generic_Data_Plan). 
    Can anyone help me to explain a further setting for this phone? I contacted my carrier but they have no idea how to set a generic data plan to work on my phone!

  • My Blackberry 8520 won't let me download the App World

    Hi,
    I recently got my Blackberry 8520 unlocked to all networks. As I turned it on, the BlackBerry App World was gone as were a few other things and my BlackBerry Messenger was not working properly. I could not recieve messages or send them. I installed the BlackBerry User Tools disk on my laptop and re-installed a few things but they still would not work and the icons were not there. I also tried to download them off the internet on my BlackBerry and it went as far as the language selection and then when I clicked select language, my phone brought me to the BlackBerry logo and just stayed there and nothing happened.
    Can anyone tell me why this is and what I can do please?
    Thanks.

    Hi,
    Nice catch on the diagnostic option change!
    I always run the advanced display, its always better to have as much detailed information as possible when you are troubleshooting a problem.
    What you described is not the Blackberry Infrastructure section referred to in the article. The first part of the test under Wi-Fi  contains the options you mention. These results refers to your device negotiating and connecting to your home router only.
    Shrink the results by clicking the first two categories of the test. The Blackberry Infrastructure is the last category. Here are my test results for reference and the options in blue.

  • Blackberry 8520 keeps repeatedly downloading the same email messages and facebook notifications

    My Blackberry 8520 has all of a sudden started downloading the same email addresses and facebook notifications, that I have already read, I tried deleting them totally and also deleted from my computer inbox, but it just downloaded the next lot in my inbox repeatedly instead.  Sometimes it says I have 50 unread messages, which is the same 7 or 8 messages over and over again, showing as unread. 
    I have rebooted device several times and don't know what else to do now, can anyone help please?
    Thanks very much

    Hi and welcome to the forums!
    Have you changed the settings for messages on your account on the providers website?
    (Gmail, Yahoo, etc.)
    If that's not it try the following:
    Go to options advanced options, Host Routing Tables, click to enter. DO NOT click on any listing.
    Press menu key, and select register now.
    You will get a verification message. Then go to email settings and send service books.
    I would suggest  logging into the carriers BIS site via PC if you can.
    You will get an email per account. Repeat the battery pull and see if the problem is
    resolved.
    Let us know how it goes!

  • Not able to use facebook on my blackberry 8520.

    Still no revert received regarding my earlier post. Not able to use facebook on my blackberry 8520.

    If you can access Facebook while on Wifi at home, but you are unable to access it while away running on your carrier's 2G network, I could phone your carrier.  You have already completed the Cellular Data troubleshooting for the iPhone, so any limitations keeping your from connecting to Facebook over cellular will have to be answered by your carrier.

  • Blackberry 8520 curve hangs, suddenly white screen comes and the only solution is to re-insert battery with power source on?

    My Blackberry 8520 curve suddenly hangs giving a white screen and when i restart it - the screen remains white. After i put it into charge - then only a successful start is done. So the only solution as of now i have - is whenever my blackberry hangs - i need to remove the battery - insert it again - and immediately put it into charging via USB/Electric-Power. Even if i re-insert the battery - the white screen comes - unless and until i put it into charging Earlier i was guessing - my battery was weak - but no such problem. pls advise.

    Hiya!
     Personally, I havent seen this so it may be isolated to your device.
     Your best bet for warranty is to call your carrier.
    It very well could be classified as physical damage and void your warranty. Or they may classify it as "manufacturer defect" and replace it.
    Its hard to say as carrier's policys are different
