I was told by someone that blackberry applications are device specific. i.e. if one application that runs on bold9000 might not run properly on bold9800 ?

Is that true ? if yes what are the limitations ?

There are OS based limitations, if you are writing an application for 4.7 OS version then it may not work on devices with 4.3 OS version. It happens when APIs used in application are available only on higher OS version.
You can minimize this issue by using APIs which are available on lower OS versions otherwise you'll have to make separate applications.

Your compiler level must be less than or equal to the target OS level.

Contrary to what pgoeol says, running a higher-version compiled app against a lower-version OS is never supported, even if you do not use classes not found in the older version. I do not recommend it.
