I was unable to download books using Kindle for Android when using Experimental Repack 20110118.1. The IQ was able to register with Amazon but Amazon would not recognize the device. I would start a download but it would stop and say that it could not read the book.
Since I started with Repack 20110116 and everything worked OK, I dropped back and all is well again.
Thanks for all the good work. Repack 20110116 works just fine for me and will save much gnashing of teeth.
