Google announced on Tuesday that they are rolling out the ability to upload and store any type of file in Google Docs over the next few weeks. It’s cool that Nokia N900 users will be able to take advantage of this service directly from their device by using the Petrovich and Pixelpipe apps.

The Ovi Store for Nokia N900 is still not open to the public, but there’s a URL trick to let you see what’s inside using your desktop browser. As expected, there aren’t many apps available and you will not be able to download anything yet.

Every web browser I use, pressing the back button loads the previous page. The one on the Nokia N900 is different by showing my recent history instead. That means click, wait for list to load, then another click to go back to the previous page. I don’t like it. If you feel the same way, a workaround is to press the backspace on the keyboard to load the previous page bypassing the history list.

I know it’s not out yet, but you can prepare by creating your own loopable wallpapers for the Nokia N900. Sometimes visuals are better than words, so I created this video to show you how to do it.
