I've been just sending pretty much every book I get from Amazon to the phone thinking I might want it. I don't know how large a archive capacity the phone has but I just want to get rid of a lot of the books. I know under my Amazon account I have to go under Manage Your Kindle and click on the + and "delete the book" but I don't want to delete them. I just want them off my phone. It's the same with my Kindle for PC. The way I've seen it explained is simply deregistering it and I've done that MANY times with the for PC and when I simply download the program again once I register it it uploads all the books I have under my Amazon account onto my archive. My phone archive is just too freaking large at this point and I just want to clean up shop and keep about 5 or so in the archive as go to if I feel like adding them to home. Any ideas? I haven't gotten rid of the app because I figure it'll work just like the Kindle for PC and just add them all back when I get it again.
