Are you looking for free Blackberry Curve Themes? There are quite a few free themes to choose from that are specifically made for the Blackberry Curve. I recently purchased my Blackberry about two months ago and was quick to get on Google and check to see where I could download free themes for my Blackberry.
Needless to say, I had a lot of difficulty finding free themes. I would find sites that said that were offering free themes but as it turned out they were not. They wanted me to beleive that they were free and on the last page, it prompted me to order or download a free trial.
I know that there are free Blackberry themes as I have seen other people have them; however, finding them seems to be just a tad bit difficult. One site that I found that has plenty to choose from is a site called BlackberryThemes.net. They have a mixture of paid themes as well as free themes.
