I would love to get a new o/s system for my 8703e. I have tried to download 4.5 but the site always refers me back to the same note. It says my phone is using the newest os. 4.1

I think you are tying to d this from the blackbeery site and have it upgrade it for you. The 4.5 is for Sprint phones. It will work on your device if you delete the vendor.xml file. Get the OS here and download it to your pc. Then left click on it so it installs on your pc.
Theres a link for proper upgrade/downgrade in my signature....use that for instructions. Get the OS here Sprint Software Downloads - Smartphones - BlackBerry� 8703e
