I'm sorry, I've research/posted around on other sites trying to figure this out...but I'm still very confused...
In the past, to downgrade, I simply ran TinyUmbrella's TSS server with an SHSH blob that I saved while Apple was signing them and proceeded to restore to whatever firmware version I wanted. Why is this somehow different for the 4S/iPad 2? I saved my 5.0.1 blob a few days ago for my 4S, so why am I not able to downgrade from 5.1 if I chose to update to try it out?
All I can find is people saying "Oh no! You can't do that!", but offer no explanation as to WHY. Having done this in the past on an iPod Touch/ATV2 (and hacking Android phones like mad), the concept of being prevented from downgrading despite taking precautions/backing things up is really confusing me.
Thanks in advance!

03-09-2012, 05:13 PM #1144Straight Upgrade to 5.0.1
Need to unlock 2each iPhone 3GS at firmware 4.1, Baseband 05.14.02. Have just spent 2 weeks on the internet and concluded I should just do iTunes upgrade to 5.0.1 and then unlock.
I understand some users have favorite games or applications that may not work, or work well, with iOS5, but that's not me.
Have I missed some benefit to saving 4.1 SHSH or Baseband with Custom 4.1 IPSW? (Perhaps something to do with the new type of SHSU I just saw Simon mention.)
Note: In 09-15-2010, Post #116, Simon stated " Sorry there is no unlock for that baseband yet. It might be awhile until there is one. " I have not keep up so I don't even know if Baseband 05.14.02 was ever unlocked; if it wasn't, then it seems clear I don't want to save anything and just charge ahead to 5.0.1
Anyway thanks for this wonderful forum.

First post will tell you what baseband can be unlocked. 5.14.02 cannot. Only the ipad baseband method will unlock that. However you cannot simply update to 5.0.1 anymore as Apple is not signing that firmware as of this morning. If you have an old bootrom 3GS then that isnt a issue, you can still go to a custom 5.0.1. If you have a new bootrom 3GS you will need 5.0.1 SHSH and APticket to be able to restore to 5.0.1. Without them you can always stay on 4.1 and unlock as Apple still signs 4.1 for 3GS.

Thanks for quick response! Your closing statement for new bootrom of "stay on 4.1 and unlock" combined with the earlier statement that the phones baseband cannot be unlocked would mean that a baseband-only upgrade (since firmware is already at 4.1) is required. For baseband-only upgrade, I only found an unattractive 06.15.00 option. I see 06.15.00 as a problematic dead end. Seems I am left hoping for a quick 5.1 unlock solution unless you can point me to something else or I misunderstand. At this moment I understand the 5.0.1 update I spent the night downloading into iTunes this week will not be activated if I now press update since Apple quit signing that firmware today.

Guess I'll put them on the shelf, charge their batteries occasionally and hope to catch another unlock opportunity.
Thanks for confirming info.
