My phone is a Blackberry Bold 9650 and yesterday I upgraded my device software from OS 5 to OS 6. Unfortunately I do not like the way OS 6 operates. Does anyone know how to delete OS 6 from my Blackberry Bold 9650 and then reinstall (downgrade) the OS 5 operating system on it? I went into a Sprint Store and was told that they did not know how to do it and that they did not believe you could "downgrade" from OS 6 to OS 5. Any help and suggestions would be appreciated!!!!! Thank you in advance for any advice or help you can give me!!!

Your Sprint people are silly..,
1. Download and install the older version of the OS.
You want to select the 9650 device and scroll DOWN to the link to download the 220.127.116.110 Multilanguage software.
(which has this filename: File name: 9650_512AMEA_PBr5.0.0_rel1675_PL18.104.22.1681_A22.214.171.124
3. Install the older OS to the PC by running (double clicking) the file you downloaded.
4. Go to c:\program files\common files\research in motion\apploader and delete the file named "vendor.xml."
5. Plug in BB and double click on "Loader.exe." It's located in the same place as the above vendor.xml file.
