So I may be an idiot, but on my stock iPad1, under "about", it says my iPad is on 4.3.3 (8J2). I've tried using Snowbreeze 2.7 with iPad1,1_4.3.3_8J3_Restore.ipsw, and get a firmware not compatible error during the "shift+Restore" part. I've tried using Redsn0w rc16 and rc18, and it froze up during the limera1n exploit. I've tried both Redsn0w and Snowbreeze MANY times each. I'm on a Win7 box, tried it in XPSP2 compatibility, without XPSP2 compatibility. Tried setting the affinity, without setting affinity. I've tried the same processes above over and over on my WinXP box, with the same problems and the same compatibility issues.
I would have to think that the problem lies within this 8J2 vs 8J3 difference, When I do a standard iTunes restore, 4.3.3 8J2 is what it gives me. Every link i have found on the internet for iPad1 is for 4.3.3 8J3. I have noticed that the os for the iPad2 is 4.3.3 8J2. Did iTunes put the iPad2 OS on mu iPad1?
