i know ab't that, but it doesn't work. 

it was working previously.

tq

My fone currently permanent stuck in DFU mode.. 4.2.1 jailbreak upgraed to 4.3.3..
it give 3194 error , but if i remove the
74.208.105.171 gs.apple.com it goes further, but at the end it gives another error 1013. Need advice here.. currently fone unusable!.

Saving SHSH blobs for 5.0 cannot be done with TU. Apple has changed something whereby the blobs can no longer be retrieved from Apple Server. Which means Cydia also cannot get it as well.

Apple wins.

You should be able to downgrade from 5.0.1 to 4.x firmware version. Below is the info taken from TU.

It just means that if you are on 5.0.1, you cannot downgrade to 5.0 (even if you have SHSH blobs of 5.0 ... probably using iSHSHit or something like that).

simple..
means that my iphone3Gs Old bootrom can upgrade to 5.0 (untethered)  (NOT 5.0.1)& still can downgrade back to 4.x la?

i cant upgrade via custom ipsw downloadable from iclarified?

dear friends, i have an iphone 4 here that has just been updated to ios5, i don't know which version it is. and the problem is, it's an us set. use gevey sim. now i can't even pass the activation part. what should i do, i'm a total noob. reading the thread does'nt get me anywhere.

but the iphone is us set using gevey sim. to get it to work here u must jailbreak right?

anybody tried this method ?
How to Jailbreak Your iPhone 3GS Using RedSn0w (Windows) [5.0]
http://iclarified.com/entry/index.php?enid=15595

able to upgrade to iOS5.0 ? & den downgrade back to 4.x?(with SHSH saved)

jus checking whether possible to pass the iOS 5.0 upgrade Untethered or not.. since it says

The jailbreak is also tethered for all devices except the old bootrom iPhone 3GS which means you will need to connect your device to the computer each time you reboot. Finally, it may be prudent to save your SHSH Blobs by following this tutorial before continuing.

ok i understand second & third

but the 1st..
what i meant is that...
now i'm at 4.2.1(like u said cant go to 5.0 that is from iTUNES or from custom ipsw iclarified?) BUT if i use custom ipsw from iclarified & using tinyumbrella to sign for me? possible to update to 5.0?

Miscellaneous

1) There is no jailbreak (yet) for A5 processor devices (iPad2 & iPhone 4S). It is being worked on. It will be released when it is complete, and tested.

2) There is no untethered jailbreak for iOS5 yet (except for old bootrom 3GS which will always be untethered when Redsn0w is used)

3) Ultrasn0w is not (yet) compatible with 5.0.1

4) There is no software or hardware unlock for baseband 4.11.xx.
There is no method to downgrade a baseband.
Software unlocks are probably a thing of the past, seven new basebands have come and gone without any exploits to software unlock them. If you require an unlock buy a FUL phone or a used phone which can be unlocked (Hint: Do some research first, many used phones are sold at cheap prices because they CANNOT be unlocked. Buying one without knowing it can be unlocked is a waste of your time & money)

5) Flashing the iPad baseband to newer 3GS phones may kill the cellular radio rendering the phone worthless forever.

6) It is too late to upgrade to 5.0. Apple closed the window

7) Hashes do not work for iOS5. If you have 4.x.x hashes, you can still downgrade the firmware (not the baseband). Make sure your host file is pointing to Cydia.

8) There is no way to downgrade, get rid of or fix the GPS issues with the iPad baseband. Just like the warnings said, it is forever. If a method should be found to remove it, we will announce it. There is no reason to keep asking post after post.

9) If you want to try jailbreaking but have no idea what you are doing: iClarified.com has tutorials, read the blogposts at the top of each page and read some posts asking about problems similar to your issue.
________________________________________________________________________________
If you post asking for a jailbreak or unlock, asking how long must I wait, complaining that you updated and now cannot jailbreak or unlock, demanding to know when a jailbreak or unlock will be released, or post a question claiming immediate entitlement for a jailbreak or unlock or any such similar unnecessary question, your post will likely just get deleted.

so now i want to jailbreak my ios 5.0.1, what should i do? i've got redsnow 0.9.9b8 which is the latest software but then when i downloaded the IPSW which is for 5.0.1, redsnow says it does not recognize it... i'm stuck now... plz help! =(

Semi tethered is can on back iphone through ac adapter but cant use cydia tweak only right?

Here is a summary of what you can and cannot do when in semi-tethered reboot state. Remember, this is only when your device crashed and rebooted on the road and before you got back to your computer to “just boot”. It is better than being stuck in apple logo:

1) Can use phone, sms (text messages)
2) Can use every other stock app on iphone.
3) Cannot use mobile safari
4) Can use other appstore web browsers such as atomic web browser
5) Cannot use mail app. You could install a gmail app from appstore or such instead.
6) You cannot use any jailbreak tweak, app, cydia until you boot tethered.
7) While in the semitether booted state, you should not add a jailbreak ios5 notification such as sbsettings to notifications during this state or your device will be stuck in a respring loop until you get home to “boot tethered”.

Those are all the limitations I have found so far. There may be some others. I may provide a more technical write up on why these limitations exist, but for now it doesn’t really matter. They just do.

now if i wan to upgrade to 5.0.1 on my 3Gs also need to update via itunes original software?

iOS5.0.2 is coming soon..

Will be jailbreaking for the first time,Iphone 4 , iOS 5.0.1 , currently downloading the iOS5 , when it's done, will be using redsnow to do it.

Any hints or pointers anyone might wanna add?

ok everyone!! new iphone4 user reporting in!
can't wait to try out the apps and games

but i was reading this thread and the discussions are like indian words to me..

hope the sifus here can guide me along with my new iphone, tq!

by the way, sorry if seems silly question to ask, but i saw my phone firmware is 4.3.2. and if not mistaken just use safari to go -->jailbreakme.com , and install can already right?

yes, i often open cydia from time to time on my sister's phone to install some tweaks for her but didn't see any shsh for 4.3.3 saved.
and when i want to update to 4.3.3 at first i thought the phone mustve a 4.3.3 shsh saved, when i open TU, i cant see any except for 4.2.1
