BlackBerry OS 4.5 Update

Some of the new features are handheld-only; some require server upgrades. If you're on BlackBerry Enterprise Server, your IT department will need to upgrade; if you're on BlackBerry Internet Service, you'll need to wait a few months for your carrier to upgrade. I've marked server features with an (S), and handheld features with an (H) to show what you'll be able to do immediately.

• BlackBerry Maps with Points of Interest (H)
• Improved media player with playlist support and automatic playlist generation (H)
• Voice note recording (H)
• Video recording on Curve models (H)
• Streaming support for YouTube and Sling Player (H)
• Microsoft Office document editing with DocumentsToGo (H)
• Native format attachment downloading (S)
• HTML e-mails (S)
• Over-the-air device upgrades (S)
• Free/busy calendar lookup (S)
• Searching the server for old e-mail messages (S)

NOTE: Install at your own risk, as this is a Beta OS and is not supported, which may void your warranty if you have any issues.

Instructions for updating your BlackBerry OS

1. Make sure you have the latest version of Desktop Manager 4.5 installed.
2. Download the latest OS for your BlackBerry model to the PC then install it to the PC by running the file you downloaded.
3. Go to \Program Files\Common Files\Research in Motion\AppLoader and DELETE the Vendor.xml file.
4. Plug in your BlackBerry via USB and Open Desktop Manager. You should be prompted to upgrade. Follow the prompts and you're on your way.

DO NOT DISCONNECT THE DEVICE.

Be patient, it can take more than an hour... Mine took about 50 mins.

If you end up with a white screen with small icons and the number 507, re-connect to Desktop Manager again and run the application loader and it should load the OS to the device.
