OK, I am seeing a lot of people still asking about the theme fix for 328. So it's time for a quick tutorial. If you are not familiar with the theme problem, it's pretty much just white bars on the left and right side of a theme when rotated to landscape mode. See bleow:
But there is a fairly easy fix for this. First you will need to change the default wallpaper to one of your own. Or if you want to keep the wallpaper of the theme, just check with the theme developer to see if they can provide you with the wallpaper. Then while on the app screen hit the BB button and select "Options". Click on the wallpaper tab.
Navigate to the wallpaper you wish to use. In this case I will use this one:
Now back out to the homescreen and rotate to landscape. Well, we aren't fixed yet are we? Almost. Now go back to the same Options menu where we changed the wallpaper. This time click on the layout tab.
Now change it from 2 rows to "Today". Hit the back key and select "Save". Go to the homescreen and back to the app screen. Now repeat but this time change the layout back to "2 Rows". Exit and save and enjoy your working theme.
Now here is the big BUMMER! The process of changing from Today to 2 Rows has to happen everytime you restart.
You do not have to change the wallpaper though.
It's a pain in the arse but at least it fixes it. Hope you find this helpful.
