I found a theme that I loved, called DC1/DC2. I can't post the link since I have under 10 posts, but it's mentioned in the article named "BlackBerry theme roundup for July 5th, 2010 - 50 free copies of osXv2 to be won!".
But then I realized it was for the 9700, and I've got the 9000. I downloaded it just to try, and alas, it didn't work.
Sooo... I was wondering if anyone knows of themes that are similar to that one, but for the 9000? Oh, and free please. I'm an unemployed student.
