Latest update V 0.48 is attached below. In summary; this update has some more ui tweaks, provides extended WEP decrypt options, provides use/management of replay*.cap files, adds injection driver checks/compatibility. Details as follows:

1) Program performs check of OS compatability with injection driver (ie. OS needs to be newer than KP46), and checks for already loaded injection driver before loading and finally activates the correct button (ie. load / unload injection button depending on loaded status of injection drivers).
2) Program now allows management of replay*.cap files as per Estel's request.
3) Extended WEP cracking options to provide UI access to most of the aircrack-ng WEP cracking command line options:
- individual korek attacks aircrack-ng -k n (n= 1 to 17);
- WEP dictionary attack;
- aircrack native characters only brute force attack aircrack-ng -c command line option;
- aircrack native hex numbers brute force attack aircrack-ng -t command line option; and
- John brute force attack (same as for WPA).
4) Minor UI update disables injection buttons for WPA APs since they don't seem to do anything for WPA encrypted APs.
5) Minor UI update scanning for networks provides a message to that effect (ie. Scanning for networks ...).

Install version 0.3 from post no 1. in this thread (or any other working version), then apply my update. As per usual, make a back-up copy of the files to be replaced (Main.py, FAS.py, getinfo.sh, scan.sh, getmacmanaged.sh, getmacmonitor.sh, wepcaplist.sh, wpacaplist.sh, keylist.sh), copy the archive to the FAS directory on your N900 and extract within xterm in the FAS directory.Enjoy
