    You are threadjacking an unrelated thread. You should know better than this (as a regular here), also you should know that the iPhone dev team doesn't give fixed release dates. There are plenty of existing threads explaining this. I guess you were too good to bother trying to search before posting.

    Stay on topic.

    It's important to note that notcom (tiny umbrella developer) is now promoting a different method for getting 4.2.1 installed on an iphone 4 while preserving the 01.59.00 modem firmware. Restoring. Before it was updating as the signature check apparently was not implemented in this method.

    You can read more about the new restoring method here: The Firmware Umbrella - TinyUmbrella: Prevent iPhone4 Baseband Update

    Yes, now we have an untethered jailbreak for 4.2.1 via greenpois0n a restore method to 4.2.1 for iphone4 is possible for only iPhone 4 with preserving baseband.

    Be sure to read that guide by notcom and follow it exactly. Many people are still trying "exit recovery mode" which won't work for a restore to 4.2.1 When preserving baseband.

    Ok, FIIIINALLY I found an iPhone 4 running 4.0 01.59.00. So I tried restoring with a Pwnage 4.2 cooked 4.2.1 ipsw, but it returns the "this device isnt eligible for the requested build" error. Pwnage did pop up the DFU confirmation windows so I dont know how to proceed. Can anyone give me a hand with it? I dont wanna attempt to do anything else because is the first i4 I try to restore to Pwnage firmware. I do need to unlock it..

    Apple has now stopped signing 4.2.1, (as of the 11th)
    So... unless you managed to save a SHSH for 4.2.1 before then for your new iPhone 4, you cannot restore any OS except 4.3 (which Apple is still signing)

    custom IPSW on any new bootrom device requires a valid SHSH.

    So my only option is to just unlock it as it is now, on 4.0?
    I want to restore it to erase all the data of the previous owner. Can I still save the 4.0 shsh and restore to Pwnage cooked 4.0? If so, which Pwnage tool version do I use for 4.0?
    Thanks man.

    It is too late to save any SHSH except 4.3

    I have documented previously how you can remove the data from the previous owner without erasing the OS. However I haven't tested this on iOS4.x

    I've said numerous times that redmond pie can't be trusted with 100% reliable solutions

    Many iphone blogs have written guides explaining how to jailbreak iPhone 4 iOS 4.3 with unofficial pwnagetool bundles, but they fail to mention a key fact:

    Most jailbreak tweaks don't work yet on iOS 4.3 This is because iOS 4.3 has created some compatibility problems with MobileSubstrate (used to simplify installation of most tweaks). Apple has introduced ASLR this randomizes the locations in memory that parts of the system are loaded, many existing tweaks rely on predictable memory locations to install and will not work on iOS 4.3.
    Ultrasn0w relies on mobilesubstrate and probably won't work because of this.

    Reportedly MobileSubstrate itself has already been patched to work with iOS 4.3, but it requires additional kernel patches that may not be included in unofficial pwnagetool bundles. Also there is no clear message about whether or not individual tweaks will need to be manually updated to cope with the now random memory location introduced in 4.3


    However I know the source of this particular PwnageTool bundles linked there ( DjayB6 - using tools made by msft.guy and for the bundle that doesn't require ramdisk fix - ih8sn0w)

    While I haven't yet tested these, they are going to work as a basic jailbreak. You will almost certianly experience problems with some mobilesubstrate addons.

    Be sure to use the PwnageTool bundle linked as "Update 1", that one includes proper patches that remove the need to "fix the ramdisk" and the very latest MobileSubstrate.
