Cryptography.... I just wondering what it’s mean, and what it’s would bring meaning to any people. I was really interested about it and make some research where I found it’s being about encrypting some method by using neither alphabets nor numbers into codes! Realize or not, it’s such a huge thing where brilliant idea that makes sense but kept in methodology in our civilization life. Whatever it is, idea or matter of geniuses from human being sometime brings a benefits to us in everyday. How to encoding or decrypting? Blow your brain with knowledge or reborn as geniuses among ordinary people, that was how u should do. Not everyone is able to adapt in solving some theorem, makes an anti gravity plane, and doing some cold fusion stuff. So there’s a different in achieving of the geniuses in some way and how to build some brilliant idea from a brain neuron by normal people. But there’s serious explanation; everything what we do, we’re always keep learning and learning will never stops! For some other people, lets them do their own stuff as long as we’re getting the profits. That was the cryptology are, numbers has been encrypted for people today’s and forward to next 13milion years ahead. It begins from fast capacitor capability counting from 1 to 1,000,000 in just a second. Small numbers ‘0’ and ‘1’ with value meaning ‘on’ and ‘off’ where it’s given by name of binary. How cool is that? Many factor has been involved in this mathematical technique, where it’s come the cryptology and the cryptology is mathematic it’s self.
Enough some bubbles! We’re out of topic... Actually I want to talk about upcoming iOS 4.2.1 Unlock and I would like to write some review about it. So, how about cryptography? Maybe ill continue this topic in my next article.
Back to the topic, there’s iOS 4.2.1 Jailbreak & Unlock for iphone 3G and 3Gs baseband later than 05.13.04 as reported by Dev-Team. I really really want this iOS to be installed in my iPhone 3G, but I’ve noticed that this iOS are (tethered) and not many people know about this as far as their not reading the manual carefully provide from the Dev-Team or maybe they missed the part of caution. Therefore, I have some old bootrom 5.11.07 unlocked and I dont want to break it unreasonable so I stick to it until next stable iOS Jailbreak coming soon. For some noob (what a shame title) to JB & Unlock such me, the guide as shown are pretty difficult to follow as long as I have no experience handling this iPhone, moreover this iOS version updates are locking the baseband after the installation to bootrom (what a nitemare). If you’re already update to this 06.15 baseband, that would mean you’ve get caught back in prison. You can’t revert, or restore it back to your old state baseband. For now, there no way to solve this issue while Dev-Team working on this! However, there’s some method and guides to Unlock your iphone 3G and 3Gs with iOS 4.2.1. If you want to do this, precaution that some iphone may have vary baseband version and its may not work to some iphone. Maybe you’ll need some luck or use some brain cells with experimenting... For those have trying using this guide or any other website method, please share your results so we can share some experience and make this tutorial better.
How To: Unlock iPhone 3G and 3GS on iOS 4.2.1
The Dev-Team has just released the carrier unlock for iPhone 4.2.1 on the 3G and the 3GS for basebands later than 05.13.04.
Here's how to use the Ultrasn0w unlock on your phone. Know that the Dev-Team does warn that if you have an old bootrom 3GS and are already unlockable, but want to get to 4.2.1 should hold off until the Dev-Team releases an "unofficial" bundle.
They also note that they will be releasing an update to RedSn0w later today for those who do not have Macs (and therefore cannot run PwnageTool) They say that the new RedSn0w will give you the option to update your baseband to 06.15 as well.
They do warn of a few things that come with downloading 6.15 and say to "do this at your own risk":
• There is no way to come back down from 06.15, and there’s no hiding the baseband version from Apple. You’ll be voiding your warranty in a very obvious way.
• If some future baseband comes out with a critical fix, you won’t be able to update to it if it remains down in the 05.xx sequence (then again, you wouldn’t update to it if you wanted to keep your unlock anyway).
• Starting with FW 4.2.1 if you have 06.15 on your iPhone you won’t ever be able to restore to stock firmware (it will fail). You’ll need to only restore to custom IPSWs (then again, if you’re unlocker you should already be doing that).
• Certainly don’t update to 06.15 if you don’t need to! Only do this if you need the unlock and you’re stuck on 05.14 or 05.15, and you’re willing to assume the above risks.
That said: Back everything up, and know that you are doing this at your own risk. Please make absolute sure that you know what you are doing. We take no responsibility if you lose data or your phone in the process.
*SHA1 Sum = adda6d882dce1b5117d01586037de289407e038a* to create your custom 4.1 IPSW. Tell it that you want to use the iPad baseband you just downloaded in step one.
3) Restore your iPhone to your new custom IPSW.
4) Launch Cydia and go to Cydia>Manage>Sources>Edit>Add
5) Then enter http://repo666.ultrasn0w.com
6) Press "Add Source"
7) After installation, search Ultrasn0w 1.2 and install the application. This will unlock your iPhone.
8) Restart your iPhone, and you should be unlocked.
