The panoramic background cab works but I have not yet found a way to wallpaper on all tabs.
That is actually something I have been working on today.
Trying to make my own workaround with no luck yet.
As for Radio, just download the most current one for your network or try any really.
I am using the latest Sprint radio and getting much better battery life.
You can always flash back to a stock radio for your network.
Trial and error my friend.
Good luck.
