I have a fairly new n810. I can access the net successfully for the most part (though some sites seem to either hang on loading, or just seem plainly inaccessible, but I can't figure out why). I have searched these forums diligently, also googled the issue, but no working answers.
OK, here's a couple of examples. As the n810 comes, even after reflashing to the latest build of the OS (which I have done) there is a folder in the browser bookmarks for Google. One would think that all the links in that folder would work, but they don't. here are the results:
Search.....perfect
Calendar...perfect
Blogger...loads fine, but the "new post" button does nothing, so the app is useless.
Docs...loads fine, I can see all the docs I have there, but when I select one a blank new browser page opens, nothing else.
Mail...says it's loading, nothing ever happens, blank screen.
Maps...perfect.

Does anyone have a clue why some work and some don't? FWIW, the settings in the browser are: Javascript and cookies enabled, cache is set to "automatic", Flash and Shockwave are enabled.

I tried restting the n810 back to its original state, this seemed to help, as before I was able to do even less with the problematical sites that I mention above.
possibly also related to this issue; When i compose an email using yahoo mail, click the "send" button, nothing happens, yet if I keep pressing that "send" button the email(s) do get sent. I know, I have sent 5 copies of the same email to recipients.
Any help and insights greatly appreciated.
