Running a BlackBerry OS6 based device? Using content encryption? Unable to attach a content protected file (.rem) to a message? No option in the context menu to send the file?
You should be able to attach a file on a content encryption filesystem (internal or media card) to an email, BBM message, etcetera but there seems to be a bug. We have encountered some BlackBerry OS6 devices running revision 184.108.40.206 containing a bug which removes the ability to do this.
Remove content encryption to work around this bug or upgrade the firmware to solve this permanently.
