If you contact Dataviz and explain that you are changing devices, they might give you an activation code for your Curve. But since you will be running a completely different program, I would not consider them under any obligation to do so.
Sorry I didn't explain better, but I am using my palm as well as my blackberry curve, so I need the documents to go premium version from the Tungsten E2 to also be loaded on the Blackberry curve 8330 without paying a second time. Is this possible
No, dataviz will require another license for your bold. Serpate license for each running version. They explain that right in their FaQ, surprised you missed.
