Why doesn't my webpage fit a small screen?

Hi all. First question here...

I'm developing a responsive site. There are 5 pages. 2 of them fit the width of the cell phone screen just fine, but 3 of them have extra space to the right. Unless I'm missing something, I THINK I have all the divs set a set width of 360px and to hide any x-overflow... (which I only applied as insurance to avoid potential scrolling!)

Here's the site: [cut]  The pages that scroll right are Home (index.html), Products and Gallery.  NOTE: You'll have to view these on a phone to see the scroll...

If anyone has any suggestions, I'd surely appreciate it. I've been scratching my head for 2 days... :/

On my end i can only scroll the Gallery page ...

You don't need a small screen, in Firefox use CTRL-SHIFT-M and you can see your website in different small sizes.

If your site is responsive then it'll automatically adjust in those smaller screens firefox supplies.

I tested your site and something wasn't right.
