For those who already payied for this great application and want to install the new version with themes and rds, you can try this:

enable developer mode
open terminal
type: devel-su
type: rootme
type: apt-get update
type: apt-get dist-upgrade

you will see that fmradio is starting to download and the device is trying to install without success

type: cp /var/cache/apt/archives/partial/fmradio_1.0.1_armel.fmradio.FAILED fmradio_1.0.1_armel.deb

type: dpkg -i fmradio_1.0.1_armel.deb
type: rm fmradio_1.0.1_ armel.deb
type: apt-get clean
type: apt-get remove
type: apt-get autoremove

Done.

On your own risk, do not blame me if something goes wrong.
