What is the newest firmware and how well does it make the iPronto work?

BlueDo told me I will have my remote by Friday so I would like to know as much as I can before hand to make the programming less of a pain.

Also when I learn buttons do I have to go into iProntedit and erase all of the actions for each button before hand or can I just learn directly from the remote and have the remote replace the old IR itself?

Thanks,
MAX
