Need advice on udating the firmfare

[mecrazycoder]

Guys rite now I am in 3.1.2 firmware(3Gs) and I want to upgrade it now. So can you please tell me which firmware as well as i-tunes is safer for jailbreak & unlock. Also I have SHSH blobs from 3.1.2 to 4.2.b3. P.S I don't want tethered jailbreak. BTW I tried restore to 4.3.3 but I am getting "Apple update server error or timeout error".Whats going wrong?. Thanks in advance

Apple is no longer "signing" that firmware, that is why you get the error message. If it's a 1013 or 1015 error message, you can use tinyumbrella to kick the device out of recovery and continue.

But in iTunes shows 4.3.3 is latest version.

Well, have you tried clicking on the check for update button? and is your PC connected to the internet? (that would play a big part in this.)

You do don't mention using tinyumbrella when upgrading...? as Hawk said

You will need TSS running in tinyumbrella while updating to 4.3.3....the latest version of iTunes is safe to use..
