This should work on Bell Mobility. This may cause the Internet icon to appear on some carriers. However, unfortunately, some carriers disable the web browser in BlackBerryOS. These carriers include Nextel, Telus, and Verizon. Cingular is now enabling the BlackBerry browser if you call and ask for it to be enabled (To save time on the same phone call to Cingular, you should also request the Wireless Internet Express added, as well as Wireless Internet Express Data Connect to add both the "wap.cingular" and "isp.cingular" Access Point Names to your account). You may want to wait a few months to see if Nextel, Telus and Verizon they will enable the web browser. You may want to try calling them and asking for it. Or you can download and install an alternate web browser such as Reqwireless if your carrier supports Internet connectivity on BlackBerry. I Installed 4.x OS from another carrier. It doesn't work!
This is because you will need to delete or rename the VENDOR.XML file located at: C:\Program Files\Common Files\Research In Motion\AppLoader\VENDOR.XML
First, install BlackBerry OS 4.x but do not run BlackBerry Desktop. Next, delete or rename the VENDOR.XML. Finally, run desktop manager to install. Help! My Older BlackBerry Is Running Too Slow With 4.x!
If you upgrade an older BlackBerry to OS 4.x, then BlackBerryOS 4.x can be slightly slower than older releases. A fraction of a second lag, for example, is normal. However, it should not be so abnormally slow as to take 15 seconds to launch "Calculator", or that an hourglass shows up for 10 seconds when you try to view an email message. BlackBerryOS should NEVER feel 10 times as slow, and if that happens, there's another problem.
However, if this happens, you need to free up memory on your BlackBerry. This can be done by removing unnecessary applications. You can even uninstall BrickBreaker now if you need to do that! You should delete all your old emails using "Delete Prior".
Model 7750's are very prone to the "frequent hourglass" problem. If you have a 7750, it is strongly recommended to upgrade to a newer model such as 7130 or 7250. One important thing to keep in mind about those slow 7750's, is you must make sure you're not already too low in memory before installing BlackBerryOS. Make sure you remove unneeded applications and delete old emails ("Delete Prior"). Since the hourglass can suddenly show up excessively on a 7750 when it runs out of memory (which happens much more often on 7750's than other models of BlackBerries). Once you free up the memory of your BlackBerry, reboot your BlackBerry by removing and reinserting the battery. What If I Want To Downgrade?
Forum member 'bfrye' made a good guide: Here is a quick install guide to your blackberry. This should easily cover reinstallation of OS and reverting back to previous OS version as well.
- Download the version of OS you want to install from your carrier's website.
- Extract or install the files from the previous step. They will automatically install into the correct location. This location will be C:\Program Files\Common Files\Research in Motion\Shared\Loader Files. Under this directory you will see directories with the model number of your device (if you installed the correct files) followed by a version number. Under these directories will be a host of .alx and .cod files. Do not modify or delete these files. They are needed to install the new OS.
- Assume the BlackBerry Handheld Manager is installed, when you plug your device in, a popup will appear and ask if you want to upgrade your device. Choose upgrade and follow the steps given by the Application Loader. If you have any 3rd party applications you would like to keep, locate and select them at this time to avoid having to reload them after the new OS is installed.
- This will also be the time the apploader will ask if you want to erase all data and reload or backup and restore the data on your device. Choose your preference and continue.
- Typically a complete OS reload with backup and restore can take anywhere from 5-15 minutes depending on the amount of data on your device to restore.
- The apploader will inform you when the process is complete. After this, the device will automatically reset itself (sometime this will take longer than a normal reboot) and once completed and on, your device will be upgraded and ready to go.
Now if you wish to downgrade your device to a previous version, many of the above steps will apply.
First, you will have to remove the newer OS from your PC. Do this by going to add/remove programs in the control panel and removing the software for the new BB OS. Make sure desktop manager is not running when you do this. After complete, restart the Desktop Manager.
When you plug in your device, if everything went well, the Desktop Manager should tell you that your PC has an older version of desktop tools than is installed on the device. It will give you an option to keep the version on your BlackBerry or downgrade to the version on your PC. You will want to select downgrade and let apploader do the work.
Should this method fail, you will have to download the file javaloader.exe from the internet. Place it in a common directory (I usually put mine in the Loader Files directory for easy access. From the directory you have javaloader.exe installed in type "javaloader -usb wipe". This will completely erase all data and applications from your devie. Now navigate to C:\Program Files\Common Files\Research in Motion\AppLoader and delete the file vendor.xml. Now plug in your device and install the new OS from scratch. Open apploader and select the USB port as your connection. It will then bring to you to the main apploader screen and all the OS packages will be listed with status as Install.
If you have question beyond the scope of this document please feel free to post them. However I suggest reading and rereading these steps to ensure you have tried the most basic and tried steps to load or reload your OS. Have fun and enjoy!
