You need to give more info like what bootrom do you have and what and if you have your shshs save in cydia

[raghavmehra]

i dont know the bootrom and i have not shshs save in cydia

[iYeow]

How did you get to iOS4.0 and preserving your BB of 3.1.2 and not jailbroken?

[eyeRobot]

If you really still have 05.11.07 on there then you are already jailbroken. Just install Ultrasn0w through Cydia.

If you are still on 3.1.2 then you can use custom firmware shift restore to 4.0 and then install ultrasn0w.

This if for old bootrom only!

[raghavmehra]

I am currently on 3.1.2 and planning to go for ios4 so i asked this question

is there a better way?

[eyeRobot]

Yes, this can be done, but do you have the old or new bootrom? What is the first 5 numbers of your serial number?

When you get to 4.0 old bootrom will be untethered, but new bootrom will be tethered.

To check iPhone 3G/3GS bootrom version:

Put your iphone in DFU mode.
(Connect your iPhone to iTunes, turn off, click power +home button for 10 seconds, leave POWER button after 10 seconds, holding HOME button)

iTunes will detect your iPhone in recovery mode.

Go To:

Start->Control Panel->Device Manager

In Universal Serial BUS Controller, you will find Apple Mobile Device USB Driver

Right Click and go to Properties, go to Details tab and select "Device Instance Path" from the drop down list box.

In that information, u will find [iBoot-359.x] at the end.


On a Mac:

Put the iPhone in DFU mode
Then navigate to "About this Mac".
From there go to "More Info...", and select USB on the list on the left.
Under the USB menu you can select "Apple Mobile Device (DFU Mode)" and that will bring up information about the iPhone.

About half way down it will have the iBoot information:
It will either be [iBoot-359.3]-old or [iBoot-359.3.2]-new.
To get it out of DFU mode just hold both the home and power button until it powers back on

To check and see if you have your SHSH files stored:
The Firmware Umbrella: TinyUmbrella - 4.00.54

Your question is very unclear. I am not even sure if you are already jailbroken now or you want to jailbreak at 4.0 and then unlock, it makes a whole lot of difference and that is why you are not getting any answer.
Since you have the new bootrom, and I assume you are not jailbroken yet.
You can unlock at 3.1.2, run Spirit jailbreak to get untethered jailbreak and then you can unlock with Ultrasn0w.
At 4.0, it is better off to wait for the new jailbreak before you can unlock.

i am currently on 3.1.2 version and jailbroken n unlocked with blackrain
now i want to updgrade to ios4 so i am asking the procedure to upgrade and then unlock n jailbreak

i hope it is clear now

[eyeRobot]

Yes, that's clear, but since you have new bootrom 4.0 will be a tethered jailbreak, so for the time being you should stick with 3.1.2, hopefully a new JB will be out soon such that you can be untethered on 4.0
