I've searched but found nothing that helped...
I'd like to develop an APP that works with older versions of Blackberry's.
But, I do not see a setting in eclipse or the project settings that let me choose. Did I miss something?
Do I have to install older SDKs?
I was hoping I could just define the operating system I would like to support, and similar to Android, eclipse will only let me use those specific functions.
Solved! Go to Solution.

In the project properties you can change the bb jre to compile with. You can download from rim ealier ones.
But I think you can no longer download anything before 5.0 now.
btw, older devices do still get OS updates.
I wouldn't go anywhere earlier than 4.5. Nowadays I would prefer 5.0+ as min. There is just so much extra api's available that adds much more functionality to your apps using newer jre's.

I installed the 4.5 JDK, but I don't see how to specifically choose this as a compiler. I'm still stuck with 6.0.0 only.
Is there another file I have to download?

Right click on your bb project
-then java build path
-then the libraries tab
it should show your JRE you are building with. To change it to another
-highlight it and click the remove button
-then click Add Library button
-select JRE System Library
-then click the Alternate JRE radio button
-the drop down to the right should display all available JRE's to choose from.

looks like you can download JDE's going back to 4.0

I'm developing some app for the range between 4.5 and 7.
In order to acomplish that I use preprocesor so most of the app is common for all versions and only a few more line codes have to be added.
Testing takes a bit longer so you can check that all resolutions displays correctly, that fliping the phone doesn't affect it in a bad way and that the usability es correct for touch and non-touch devices.

Yes you can, but they are broken if your on OSX.
I've managed to get it to allow me to use the 5 SDK but replacing the bin directory, but I don't have any edidence that its going to work yet.
I hate how I have to hack a development tool to get it to do something it should already be able to do.
