The first thing is that there are two different types of OS that you can install: one is the official OS, released by a carrier, and the other one is a leaked OS, meaning that it has not been approved by the carriers to be installed.You can install an official OS using Desktop Manager, but usually it will not let you install a leaked OS unless you do some tweaking.
Once you've got that - simply delete the file there (even if you've deleted or think you've deleted it in the folder previously) and voila, it will allow you to update to the newly installed OS! Plug in BB and double click on "" It's located in the same place as the above file.
The process takes about 45 minutes to an hour depending on how much data you have to backup and restore during the process.

Download the above OS file to the PC then install it to the PC by running (double clicking) the file you downloaded. Go to c:\program files\common files\research in motion\apploader and delete the file named "" Vista/Win7 users: In the apploader folder, simply click on "Compatibility files" to see the actual file.
Any smartphones running an earlier version of the Black Berry OS could not be updated to version 7.0.
It has now been superseded by the Black Berry 10 operating system, but is still sold by Black Berry on its smartphones.
The Black Berry platform is perhaps best known for its native support for corporate email, through Java Micro Edition MIDP 1.0 and, more recently, a subset of MIDP 2.0, which allows complete wireless activation and synchronization with Microsoft Exchange, Lotus Domino, or Novell Group Wise email, calendar, tasks, notes, and contacts, when used with Black Berry Enterprise Server. Updates to the operating system may be automatically available from wireless carriers that support the Black Berry over the air software loading (OTASL) service.
Third-party developers can write software using the available Black Berry API classes, although applications that make use of certain functionality must be digitally signed.
Once it's done loading the new OS it will reboot (it may do this twice during the entire process.) You will see a white screen with an hourglass for up to 20 minutes at a time while the DM says "waiting for initialization." If, for some reason, you end up with a white screen with small icons and the number 507, simply connect to the PC again and run again and it should load the OS to the device.
Previous OS version: one thing I hate when I install a new iteration of the OS is having to re-accept the license agreement with a lot of the apps and in some cases having to hunt for the activation key to enter again.
(I did this via entering the password 10 times incorrectly.) I don't know if I need a new OS & Service Books or just service books, or something else.
