A new guy..
Just to be absolutely sure.
1. I downgrade my 5.3.3 running device to 5.3.1 with this
2. I copy jailbreak.sh and MOBI8_DEBUG into the root directory and jailbreak.mobi into the documents directory (files from the zip attached to the first post) and apply the JB as described in README
3. I update to 5.3.3
4. I repeat step 2 in order to reinstall stuff?
How about JBpatch, etc.? Can install them after updating to 5.3.3?
