I have 3G, 4.0, Jailbroken with redsn0w:
I cannot get this to happen
I got as far as getting it to 3.1.3,
blaickrai1n wouldnt work
took it to a diff pc, blackra1n worked, but then
I had no at&t service, so I had to restore it again back to 4.0
NOTHING, is working for me
I had 3.1.3 jailbroken, upgraded to 4.0
jailbroke and now I cannot get back to 3.1.3, or 3.1.2.

I did click make my life easier, then broke my screen, got a new phone with 4.0.2 tried to downgrade to 4.0.1 and got several different error messages in iTunes. My question is, am I able to get my shsh blobs from Cydia if it was for a different device? or are the shsh blobs device specific?

Shsh blobs are device specific, that's what sux about getting a warranty replacements

Anyone who's kind and smart and pro enough, please tell me that my 3G will not lose anything for downgrading iOS4.0.1 to 3.1.2, cause my latest 3.1.2 backup is a year old and lots of things changed during this year...

If u downgrade, you can only restore from that 3.1.2 backup. The new iTunes will not let you restore a 4.x device back to 3.x so you have to have an old backup to use.

Don't know near as much as most of you here but could he get an older version of itunes and make it happen?

To downgrade, he will HAVE to have an older version of itunes (i think 9.0 maybe or 9.1.1 at the latest) to downgrade.
Unfortunately, an earlier iTunes has no effect on the downgrade process as a whole: the 4.0 upgrade required us to upgrade iTunes to 9.2 (or something like that). So, (i think) you can't downgrade to 3.1.2 with iTunes 9.2 & you can't install 4.x without iTunes 9.2.
Also, when we sync, we usually let iTunes backup our phones automatically before and after we upgrade FW. The down side to this is when you downgrade (using iTunes 9.1.x) and then try to restore your previous info, it will not let you restore since your recently saved Backup is for 4.x not 3.x!!! Basically, ur stuck UNLESS you saved/moved your BEFORE backup somewhere else OR you stopped iTunes from BACKUP after the FW upgrade.
Hope that makes sense!
