Try it.
I already posted a full proof solution but I don't think you wanna follow it..

It's not that I don't want to, its that I don't know 100% on how to do it. How do I make the ipsw? Does ifaith work on a PC?

EDIT: Found my answer..

So run this program, dump SHSH. Restore to 4.2.8. Then within ifaith, run the "build signed ispw from blob", then redsn0w?

I thought itunes didn't have 4.2.8 though? If he jb'd the day he got the phone, what are the chances he'll have a backup of 4.2.8 saved? Especially if he's synced since?

A new ifaith is out. If u can wait I would ask u to wait little. Let some ppl test it then try it. Or u will b stuck with 4.2.10 :)

OK.. so wait to see that the latest ifaith works well, then run this program, dump SHSH. Restore to 4.2.8. Then within ifaith, run the "build signed ispw from blob", then redsn0w?
