1) Download New BlackBerry OS Software
First things first, you'll want to download the new BlackBerry OS and save it to your PC. To determine what OS version you're currently running, click the Options icon on your BlackBerry home screen and select About. Your OS version will be listed as a series of numbers after a lowercase V (v4.2.2.184) on the first screen. You can also employ the Help Me screen shortcut to determine your current OS version by hitting ALT, SHIFT and the letter H.

2) Download and Install the Latest BlackBerry Desktop Manager Software
Next you should ensure that your PC is running the latest version of the BlackBerry Desktop Manager, which is v4.5.
To check which version of Desktop Manager you currently have, you should launch the program via Windows Start menu > All Programs > BlackBerry > Desktop Manager. Then click the Help tab on the main screen and choose About BlackBerry Desktop Manager. The software version will be listed on the General tab.
If you're not running Desktop Manager v4.5, visit RIM's site and download and install the latest version of the software.
3) Prepare for New OS By Noting Apps, Services or Setting That Could be Affected
Installing a New BlackBerry OS will return some of your custom settings to the default options and may require you to log back into and unlock certain applications. For instance, your font family, font style and size will revert to default settings after the OS install, so you may want to go into Options > Screen/Keyboard settings to make note of your custom settings.
Many third-party apps will also require you to reenter your user name and password, so you may want to make note of which apps require a login and make sure you've access to the necessary information. For example, your Viigo RSS reader will prompt you for login information the first time you try to use it, as will Facebook for BlackBerry, your Twitter client and the Flickr app. I also noticed that the color of my jazzy new CrackBerry launcher changed from orange to cyan…
It's a good idea to switch back to an official RIM theme if you're using a third-party option, at least at first, because some features of non-official themes won't work properly on the new OS.
And it's worth noting that applications are meant to run on specific OS version so they may not work at all after you upgrade. The Freedom Universal Bluetooth Keyboard, which I reviewed for CrackBerry in May, functions along with an application that will only work on BlackBerry OS v4.0 through v4.2.
4) Open New BlackBerry OS and Begin Installation
After you've prepared for the changes that come along with a new BlackBerry OS, you'll want to begin the installation process. First, close all related applications and services on your PC and launch the .exe file. Choose Run and select the appropriate setup language.
The InstallShield Wizard for BlackBerry will then appear. You should click Next and then on the following screen choose the country in which you're currently located. Accept the terms of service and hit "Next" again. When the install process is complete, the program will ask you if you want to start the BlackBerry Desktop software. Fill in the check box next to this option and then hit "Finish."
Install OS4.5 onto your computer
From there, hit the Options tab beneath the Data Preservation and Device Backup heading and ensure that the Backup Device Data Automatically During the Installation Process box is checked. Then hit OK.
You can also click on the Advanced tab on the right side of the Desktop Manager screen to add or update applications that weren't included in the default list. For instance, if you deleted your BlackBerry Messenger app in the past but now want it back, you can hit Advanced and fill in the check box next to BlackBerry Messenger and the program will be installed along with your new OS.
You'll know your new OS is installed successfully when the Desktop Manager's Update Complete screen appears and your device's radio turns back on. Shortly after the process finishes up, you should receive a message in you inbox to let you know your device is registered with your carrier's network. If you don't receive such a message, resend your device's e-mail service books. You can send service books in two ways, using either your BlackBerry itself or your carrier's BlackBerry Internet Service (BIS) page. To send service books via BlackBerry, open your E-Mail Settings/Set-Up Internet E-mail icon, log in if prompted, and click Service Books option under the Settings heading. On the following page, send the books by hitting Service Books again.
Close out the Desktop Manager, disconnect your BlackBerry and you're good.
Done - OS Successfully Updated!!!
Notes
- If you use any BlackBerry Internet Service (BIS) accounts, you likely want to resend your e-mail service books even if you're device was automatically reregistered. This ensures that you're taking advantage of any related tweaks that may have been included in the software update.
- Immediately following your upgrade, you'll be prompted to log back into a number of applications but some you'll need to manually open to enter your account information. If you have a media card installed, you'll also be asked whether or not you want to turn your BlackBerry's mass storage mode on, regardless of your previous settings. You'll also be asked if you want to run through the BlackBerry Setup Wizard.
- If you're on a BlackBerry Enterprise Server (BES) you should check in with an IT representative before attempting to upgrade your smartphone's handheld software, because some IT policies can block or partially block a new OS install.
