I did this method (I want to say someone posted this in another thread, but not 100% sure) myself and it worked fine. I didn't have to reinstall anything or change anything. Picked up reading in Aldiko right where I left off before updating. You'll need to get Rom Manager from AppBrain and then download the updating file. No partitioning of SD cards, no wiping of SD cards. It was easier than the autonooter process imo..
