On which web pages can I find themes for siemens s65

You can find themes by looking at this post, move the mouse up untill u get to the "Adbot" area. Then u move the mouse to the left, past the light brown stripe and stop. The themes button should be in 3cm radius....

I had a Siemens CX65 before my new V600i, and I found a great site for themes, well one or two in fact:

http://www.s65.info and click on the english flag on the left, then downloads>themes

http://www.mobile9.com has some great free themes (click on gallery)

http://themes.modopo.com has a load of free themes for all sorts of mobiles.

Hope this helps you!
