Do you have a BlackBerry that’s no longer the newest model out there and you’re tired of it’s simple black text on white background? If so, you should breath new life into the device by updating it with a newer OS. By going to your service provider’s support section, you are able to download and install a newer OS which will make the user interface easier to use, fix known issues, and make it nicer to look at in some cases. The biggest improvements are with the BlackBerry 8800 series, 8300 series (Curves), and 8100 series (Pearls). The UI goes from simply black text on white background to sections that are formatted and separated. It makes it easier to read and easier to browse. The individual carriers’ download locations are as follows:
Verizon Once at the site, you are able to select your model from the drop-down menu and the appropriate download link will appear.
AT&T Go here to update your AT&T device or download desktop software. Simply select the device that you are trying to upgrade and the download links will appear. 
Sprint Once at the site, use the drop-down menu to select your device. Once selected, the appropriate downloads will appear.
