I have a Sprint BlackBerry Curve 8330 that I up graded to 4.5 and now the 8330 has no "Roam Only" option. Have been trying to download from everywhere that offers the 4.3 program but have a problem with trying to install the program after download. It says, "not a valid Win32 Application". I can start a download that says it will take about 1.1 hours or so but the download finishes any between 10min. to 40min. Is it not finishing the download or is there other people having the same problem...
4.3 or bust!

you could click on the link above for the 4.5.0.131.

If you scroll down a little ways (inside the Blackberry website) below the 4.5 you will see a link for the 4.3.

You will have to uninstall the 4.5 off your computer before you downgrade though. If you don't, it won't recognize the older version.

You have to give it no choice (showing it only one version, the 4.3). It will ask you if you want to downgrade, or something like that.

Hope this is what you're looking for.
