Kde 4.1.3 beside kde 3 on 8.04

[David McGlone]

I want to install kde 4.1.3 alongside kde 3 on 8.04. Kubuntu's website said to 
check the unsupported updates in adept then click the upgrade button. Does 
this mean the "full upgrade" button or the "version upgrade" button.

either button sounds like it will overwrite my kde3 and I don't want that, All 
I want is the latest release of kde 4. Looking at adept with unsupported 
updates enabled, kdebase-kde4 is still at 4.0.5. I want 4.1.

Can anyone shed some light on this?

TIA
