So, yeah, that was stupid. There was a space added to the client id which I finally noticed after I traced all the URLs in the webview. Problem was: The webview up until now was pretty self sustaining as I didn't need to know what went wrong in there as Instagram handled all the data and process. So this went unnoticed and obviously the client id wasn't accepted by Instagram as is was wrong.

Solution: Delete blank after client id *duh*

New version 0.5.1 (public beta) is here: http://code.google.com/p/n9-developm....5.1_armel.deb
