I found where the K3 has 3GB available for the user, and I'm already using 4GB on the external storage of my K1, plust all but 12MB on the K1 memory. I really wish they wouldn't have taken that capability away on the new Kindles.
I also found that I am in a 3G deadzone for the K3.
I'm grieving the demise of my K1 more and more.
