If you're doing this in Java you can use the BASE64Encoder and write to a new encoded file: 

import sun.misc.BASE64Encoder;

     public static void main(String[] args) throws Exception {

        File inputFile = new File(yourUnencodedFile);
        File outputFile = new File(yourEncodedFile);

        BASE64Encoder encoder = new BASE64Encoder();
        encoder.encode(
            new FileInputStream(inputFile),
            new FileOutputStream(outputFile)
        );

and then just use the encoded output file

See this java-me Base64 class for encoding with base64 format.

For more examples check koders or this Java and ME blog post: Base64 encode-decode in JavaMe.

Since BlackBerry is a J2ME environment, you can't use regular J2SE clases such as sun.misc.BASE64Encoder - but there is a native Base64OutputStream class which should serve the same purpose. See the javadocs for more info.
