I had developed a small application recently using jde 4.2.0.and on simulater it worked fine.but i have an older phone...7100v on which i had os 4.0.2.
so when i tried the app on (simulater as well as device) i got an error "out of memorry".i read somewhere that version mismatch could a reason for this.so i compiled the same code in jde 4.0.2 and it worked fine.but when i used the same cod file on simulator for 4.2.1(simulator 8100) it again gave me an error .basically a code complied on one jde version does not work on other.

now i had an app..downloaded from internet it did not specify anything abt the version and works fine on both versions.

so how do i make my code version independant....am i missing something here....pls help!!!

The BlackBerry OS is (generally) backwards compatible, but the JDE isn't. This means when you build an application, you use the JDE version of the lowest OS you want to support. So if you want to support phones with 4.0.2, use the 4.0.2 JDE or lower. If you want to take advantage of new features in the OS, you have to create separate binaries built with separate versions of the JDE. If you're not using any new API's, there's no reason to use the newer JDE.

Of course, you end up with multiple JDE's on your development box.
