2. The most recent BlackBerry Desktop software is available here: http://www.blackberry.com/support/index.shtml

In most cases it is also possible to install an update from a different carrier (if they have the same BlackBerry model). This might be useful if your carrier does not provide the most recent version you need or you want to have a special foreign charset support. For example, you can install the “Hong Kong CSL” version to have Chinese character and input support (the Operation System will still be English).
To install a OS update from a different carrier you have to delete C:\Program Files\Common Files\Research In Motion\AppLoader\VENDOR.XML first.
