Hello everyone,
Here is a quick and easy way to upgrade the OS on your phone if you wish to upgrade before the VZW official comes out. Plug your phone in, open Desktop Manager backup what you want then close Desktop Manager, and follow these instructons.
1. Download (if you haven't already) and install OS onto your computer. You can download it here. https://www.blackberry.com/Downloads/entry.do?code=A928731E103DFC64C0027FA84709689E
2. Navigate to C:\Program Files\Common Files\Research In Motion\AppLoader and delete the vendor.xml file.
3. In the same folder C:\Program Files\Common Files\Research In Motion\AppLoader double click the Loader or if you're having trouble you may have to right click and choose run as administrator (its the one with the pic of a phone) file, click next and it will show your pin click next again. It will go through a couple of steps and then a box will pop up with what is going to be installed. You can also remove or install things here.
4. After OS installed open Desktop Manager and reinstall your backed up files, contacts,sounds,bookmarks, etc.
