Just wanted to give a feedback on the JB.
Used Absinthe 0.4, all went smoothly/ very easy and now have one very happy classmate :)

Want to thank everyone for their advice/ input and this get forum :)

Just out of curiosity what are you trying to do? (aside from trying to start TSS)

Ok, thanks for clearing that up and that answers my question as to use the Absinthe tutorial.

On a side note, wonder why the i4s and iPad2 wording has been added to redsn0w when one is told it is not supported (after putting in DFU mode)?
The wording gave me the impression redsn0w would support/JB A5 iDevices.

OK???
When I start redsn0w 0.9.10b8b, under Jailbreak is states: iPhone4s and iPad2, please connect it in normal mode (iTunes mode) now.
So if redsn0w doesnt support A5 iDevices then why is above written in the program?

Hi,
One of my son's classmates has just got a FUL i4s on iOS5.0.1 for his birthday.
He would like it JB and as I have never JB i4s before (have done plenty of i4 with redsn0w), just wondering which is the best approach: using the Absinthe 0.4 tutorial from iClarified or using redsn0w 0.9.10b8b?
Have skimmed/scanned the last 30 pages without finding any clear answer.

You cant!
If you have an iPad2 with saved 4.x hashes, you can in fact downgrade to that 4.x but you won’t be able to get to 5.0.1 once the 5.0.1 signing window is closed (even if you saved your 5.0.1 SHSH blobs).

Use this tutorial to upgrade to iOS5.0.1. It works for Windows also. https://docs.google.com/file/d/0B0G5a5R3PlhfYUF1O...

You need to make a Custom IPSW to bypass the 'signing' check.
Use redsn0w under Extra to create a Custom IPSW.
Then put your iPhone in Pwned DFU and use Shift-Restore in iTunes.

If you are talking about cracked games then the other iDevice has to be JB and have AppSync installed.

Honestly, I dont know as I dont own a A5 iDevice myself.

If you need the SHSH blobs in order to downgrade/restore to iOS5.0.1 then you can forget about it ref what Dev-Team has stated:
•If you have an iPad2 with saved 4.x hashes, you can in fact downgrade to that 4.x but you won’t be able to get to 5.0.1 once the 5.0.1 signing window is closed (even if you saved your 5.0.1 SHSH blobs).
