JPEG

I saved a 1x1 white pixel jpeg at highest compression with photoshop and it ended up being 8KB. After opening it up with a hex editor I was able to get rid of 7KB of extraneous junk. So is there a way to get photoshop not to add crap? or is there a program out there that will remove this stuff by the batches?

Well I need to minimize the file size of the jpeg pictures I want to send to my cellphone, obviously so that I can store more. If it is possible to greatly reduce a jpeg's file size by removing junk data in it, I would be interested in knowing how to.
