Hi, the error "GetMasterBlock: Error 16 opening /dev/md0" is a "normal error".
If the command "mount_hfs /dev/disk0s2s1 /mnt2" gives no errors, then the data 
partition should be accessible in /mnt2. Does "ls /mnt2" lists any folder ?

Yes it does! Thanks so much, everything seems to be there that I need. I'm 
using WinSCP to get the files, but when getting photos it freezes my computer. 
What other programs might work better so it doesn't freeze?

Also, I never had my ssh saved. I used ifaith 1.3.2, and it was able to export 
my 4.3.2 blob correctly, but when I try to create the custom ipsw, when it gets 
halfway done it gives a xpwntool.exe failed to initialize properly. Driving me 
nuts. SO I have the shsh blobs from Ifaith 1.3.2, but can't seem to build the 
ipsw before it crashes. DOn't know what else to do. Could I try to use the blob 
created by ifaith 1.3.2 and install an older version of ifath and try with the 
blob created by the latest version? The blob should be the same? Also, don't 
know if that blob can be used with other methods to do the ipsw with no errors 
in itunes.

Then I found this below. Would this work and be safer?

It says "Usage:
Use current firmware version that is still being signed by Apple (4.1 ATM)!
"
I'm on 4.3.2, does this mean I can use this?

I'm new at this and am learning. I also don't now the order of steps to do this 
on my jailbroken phone. At what stage do I restore my phone from my apple 
backup? Do the custom ipsw first, then rejailbreak? Then restore from apple 
backup?

Is there a way we can chat on IRC.
