This app shows up on both Sprint (Froyo 2.2.1) and Virgin Mobile Samsung Intercept (Froyo 2.2.2) phones (I have the VM Intercept, my roommate has the Sprint Intercept).
It does not show up on my Virgin Mobile LG Optimus V running Froyo 2.2.1
This Task Manager could very well be licensed to a private individual/company that Samsung paid to use their app on the phone. Much like the Cool Iris Gallery that's on the OpV, but not on the Intercept.
Just my theory.
