Thank you for the great list of extensions. I did a jailbreak on my PW1, and it works fine! However I can't get rid of the "Personal" tag on each and every book cover I have. I usually email my books to amazon to get them sync to my device. This would keep them in Personal documents, and sync page read on all my devices. The only drawback is that they get a label "Personal" on the book cover. This is driving me crazy. Looks so lame.

Anyway I could get rid of it? Should be possible as it's jailbroken.
Any help would be appreciated!
