for people who asked me how it works
here are the steps ( they are on the previous pages )
1- download the files in the 1st post
2- install them by dpkg -i command
3- run whatsapp
4- type any IMIE and your phone number and the small textbox for
the land code
5- activate it by voice
6- you will now get the code
7- now exit the app and open it again it will ask u for the code
8- you will get the unknown error
9- edit the prefs.xml
using vi or midnight or leafpad(i used it )

here is how to edit the prefs.xml
a- open xterm
b- go for root
c- type "cd /home/user/.java/.userPrefs/org/peterbjornx/whatsapp"
d- leafpad prefs.xml
edit it to be like this

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE map SYSTEM "http://java.sun.com/dtd/preferences.dtd">
<map MAP_XML_VERSION="1.0">
<entry key="CC" value="Area code goes here"/>
<entry key="CONTACTS" value="-"/>
<entry key="IMEI" value="35*************"/>
<entry key="LOGIN" value="areacode + phone number"/>
<entry key="PHONENR" value="Your Phone number"/>
<entry key="REGSTEP" value="-1"/>
</map>

and then open the whatsapp again and tadaaaaaa its working :O
