[Samsung Epic 4G Touch] CaptainMorgan:
1. You can find previous builds in jafterdarks thread but I would only recommend this weeks release, the others where a learning experience for me.

2. I tried including his kernel but that so far is out of my scope. Also, included kernel FE22 does not include custom recovery.

3. Changelog copied and pasted from the Facebook page:
