My iPhone4 is unlocked JB untethered.
=32gb
=Firmware 03.10.01
=ISO 4.2.1
=T-mobile
=Window XP Home

Can I upgrade 6.x.x or Don't an upgrade ?
I've tried but I can't because it's disappeared. Lemme know...

[EVO]

yes you can upgrade...

what you need to do is create a custom 6.1.1 firmware to preserve the 03.10.01 so it can work with the gevey sim you're using (i'm assuming, unless its been unlocked from Apple)

then you can download the evasi0n jailbreak from the evasi0n.com website

Can you tell me how to do this which is first installed. then what's next?

@EVO , I'm agree with u. But am waiting for them the answer n who know it.

[EVO]

What you need to do is download the 6.1.1 firmware from here:
Firmware - Downloads - Apple, iPhone and iPad Forums | ModMyi.com

Look for the iPhone 4 GSM 6.1.1 version

Then download redsn0w from here:
Dev-Team Blog

Then open up redsn0w and click on EXTRAS, then CUSTOM FIRMWARE, and point it to the firmware you downloaded

It will create a custom firmware for you.

Once its done, click on PWNED DFU and follow the instructions to put your phone in a restoreable state.

Then you need to open itunes and hold the SHIFT key while clicking on the Restore button in Itunes and point it to the redsn0w firmware that was created

Is there anyone you can recommend to do this for me.

The correct answer is possibly but not yet....

First thing first, you need SHSH to stitch a custom iOS 6 fimware. Run Cydia on your iPhone and check if it has saved any untethered jailbreakable firmware (6.1.2 or older). If so then you may upgrade/downgrade to a jailbreakable fimware. However, as of today, 03/23/2013, iOS 6 SHSHs are not ready for stitching yet. Give the devs some time to prepare and wait until they give the go ahead.

Note that I'm assuming you want an "untethered" jailbreak. If not then you may do a tethered jailbreak on the current firmware. I'm not sure if Redsn0w does it now. I don't pay any attention to tethered, so I don't know. You may want to check.

Good luck ....

You are undeniably and utterly correct sir.

Good catch!

I forgot redsn0w has not support stitching "yet" and there is an issue with sn0wbreeze leaving iphone 4's stuck in DFU after restoring to iOS 6.1x..

So it is under close observation that this is not possible, as of this moment...

I apologize for the misleading information..

No problem at all, Evo.... The whole purpose of the forums is to share/learn from each others.... Also, thanks for your efforts to keep modmyi running strong ... Cheers!!!

[EVO]

HOWEVER..............redsn0w DOES allow support stitching of iOS 6.0 firmware, just not 6.0.x and above

I wanted to clarify this for anyone who do want to restore to 6.0 (except iphone 4s/5) that they can, provided they have 6.0 shsh blobs

But it should only be a matter of time before the developers find a solution to this issue

Below is the latest info on restoring A4 idevices to iOS 6.1.2 or older iOS 6.x from iPhone developers team:
