iOS 8.3, 8.2, and iOS 8.1.3 are not jailbreakable. There is no way to downgrade from iOS 8.3, 8.2, or 8.1.3 to earlier versions.
Instructions for jailbreaking iOS 8.0-8.1.2. See /r/jailbreak on Reddit, @PanguTeam, and @TaiG_jailbreak for updates.

What is the difference between iPhone 4 GSM and the "Rev A" variant? And how do I know which I have? There are different IPSWs "Phone3,1 6.1.2 10B146 Restore.ipsw" and "iPhone3,2 6.1.2 10B146 Restore.ipsw" - that is 3,1 and 3,2 files. I want the right one to stitch !

Models ME798 and ME799 are iPhone3,2 (GSM Rev A) and any other iPhone 4 GSM is a iPhone3,1 (and this links to additional info.).
