Thank Everybody! So much help from You guys. So in order so solve my "problem" with the kernel i have just clicked Deinstall Kernel blablabla in the menu and then reinstalled kernel power. And i wanted the 42 one because it's in extras, and 46 is in devel, so i am a bit scared of losing all of my stuff even with the new backup app, that's just my opinion. if You can tell me why should i switch to 46, i'll think of it. Thank again for pointing out the folder of png and desktop file. I kinda knew it... but still..
Out of curiosity, how is John the Ripper handling the cracking? In my experience, it needs a wordlist, right? Obviously we don't have huge wordlists on our n900's =P I captured my home's WPA handshake successfully, but it was draining my battery trying to crack it, so I uploaded it to my quad-core linux desktop to crack it myself, but I realized that I use aircrack-ng with the "-w" to specifiy a wordlist. I suppose my question derives from my ignorance on all of JTR's functions.
