I noticed, that the Mobile Internet Toolkit 3.1 with Nokia Mobile Browser 3.0.1 has problems with posting:

1. I load an xhtml page with a form containing some data
2. I post the form with data
3. I return to the form page with back-button. As the page is not cached it gets reloaded with new post data.
4. When I re-post, the browser seems to post the old data; not the data, which is contained in the page and can be seen e.g. in the page source!

The problems seems to be the use of 'Back' button. If I reload the form, or access it using a link, the new values are posted correctly.

I hope this can be solved!
