Using methods by The Skizzy, I figured out how to get PSPRadio and PSPKick working on 2.6
Although, his method requires "formatting your memory stick"... this is unnecessary, you just need to have the eLoader save game Auto-Load...
Then install them the way its suggested for 2.01+
The only problem I have now is that PSPRadio freezes when you try to exit... other than that, it works great... and so does PSPKick
Note: Using latest versions of both apps, and latest eLoader (not alternative)
