Kde 2.2 Beta1

[Laurent Rathle <lrathle@teaser.fr>]

Hello,

Which is the best way if I want to install Kde 2.2 Beta1? I've downloaded the 
.deb from ftp.kde.org. Could it cause any problem for any future update with 
apt-get if I install this version? 
I'm using "testing". Should I use "unstable" instead to have Kde 2.2 Beta1, 
or is it still to risky?

Thank you,
