Yesterday we reported you that the new hacker guy Pod2g has found an exploit to jailbreak iOS 4.1 after releasing with few hours, but till now there is no news about the baseband exploit, so the dev team warnned the upgrade to iOS 4.1 as you may lose your unlock may be for ever. Fortunately Notcom, the guy behind Tiny Umbrella, with version version 4.1.3, he discovered a method to preserve your iOS 4.0.1 baseband 01.59.00 while updating to iOS 4.1 on iPhone 4.

Yes, you read it write! Now you can downgrade the annoying new iOS 4.0.2 to iOS 4.0.1 or iOS 4, without having your SHSH blobs saved. YES! without SHSH blobs. The tip was sent to us by one of our readers who wishes to remain anonymous, we made some tests and we got our conclusion at the end of the post.

A few minutes ago iH8sn0w has just posted on his twitter that he is about to release the Sn0wbreeze 2.0 after few hours, after he finished the integration between iREB and Snwbreeze 2.0 we have mentioned before, that sn0wbreeze 2.0 will jailbreak iPhone 3GS (Old Bootrom) on iOS 4.0.2.

Early today we told you that Apple has stopped signing SHSH blobs of iOS 4.0.1 and iOS 3.2.1, So Notcom has updated his popular tool "TinyUmbrella" to be able to save SHSH of iOS 4.0.2 for iPhone / iPod Touch and iOS 3.2.2 for iPad.

A few hours ago Apple has blocked the digital signature for the firmware 4.0.1 and 3.2.1 , so now it is impossible to restore to an earlier iOS version. From now users can't save SHSH files to Cydia or Apple for iOS 4.0.1 and 3.2.1 or lower.
so those who upgrade to firmware 4.0.2 will no longer able to restore or unlock their iPhones, in addition who upgrade his iPad to 3.2.1 will no longer able to unlock his iPad.

As we all know that Apple has just released the new version of iOS 4.0.2, but for all those who are not satisfied, or want to downgrade to a pervious version of firmware can follow the guide below.

Comex has just released his new userland jailbreak tool minutes ago, this is a simple guide and instructions for all you need to know about this jailbreak, Now you can jailbreak any iPhone (including iPhone 4), iPod Touch or iPad on all Firmwares.
Steps:

Just found iOS 4.0.1 Custom Firmware for iPhone 3GS Old Bootrom to Jailbreak iPhone 3GS with the Easy way without need to launch Sn0wbreeze or PwnageTool and create your own Custom Firmware, Here's a ready Custom Firmware, all you have to do is to restore with this Firmware using iTunes..
Note:

Well, Planetbeing today has posted on his twitter account that he has already updated to iOS 4.0.1 on his iPhone 4and that was a good thing to find that it's unlockable with taller bars. This unlock is the one that Planetbeing used before and Musclenerd said that it's the best and they will use it on the new update for Ultrasn0w.

Well, this post wasn't important but I think most of you thought that Semi-Spirit Jailbreak for iPhone 4 would be out at the end of this week? nope, you may need to read this post. I will talk about two points, the first is that the Jailbreak is delayed due to some issues in FaceTime and Multitasking, Second point is that most of you think it's "Spirit" but due to some sources, It's Not!

Tpday, I already posted a guide to Jailbreak iPhone 3G and iPod Touch 2G on iOS 4.0.1 using Redsn0w then Unlock using Ultrasn0w 0.93 for Both Windows and Mac Users, But A lot of people asked me about iPhone 3GS (Old Boot), I didn't leave them back.. I already found a way using PwnageTool which has been achieved by Criminal 90 ToolJail Author, So Let's begin the Jailbreak..

I know that you have waited this update a lot which should fix antenna issue (reception issue) in iPhone 4, the new update FW iOS 4.0.1 from Apple has been Released today for Public and it's avaiable for download and upgrading to it, The way is simple but take care!
Yes I mean take care, Don't Upgrade Until we tell you. Let your family and friends away from iTunes and let your hands away from Update button because it really hurts without Jailbreaking and Unlocking.. The Dev Team will Release Jailbreak for iPhone 4 and iPhone 3GS New Bootrom (by comex) and Unlock iPhone 4 (by planetbeing) Soon! So Stay tuned on Twitter.
