Re: when to sign ?

First, you have posted in the wrong forum...There is a dedicated forum for developer questions.  Please ask a mod to move your thread to the proper forum.

 

As for signing keys, they are needed for certain secure api's.  I don't know off the top of my head if the api's you are calling require signing.  However, if you're developing apps, you'll want to get the signing keys because you will need them sooner or later.

Re: when to sign ?

The BlackBerry JDE and BlackBerry Java Plug-in for Eclipse will present warnings if your application requires signing.  You can also refer to the JavaDocs.  Any class that requires signing will state so and have lock icons shown beside its methods.
