Remember msft.guy? who fixed the blacksn0w unlock for iPhone 3.1.3 05.11.07 baseband? and who recently released binary which enabled blacksn0w unlock port for iPhone 3GS, on iOS 4 Beta 4 (formerly iPhone OS 4). Well the guy is back now! He has posted PwnageTool bundles for iPhone 3GS, iOS 4 GM release which you can use to jailbreak your iPhone 3GS, while preserving your baseband so that you can unlock using ultrasn0w or blacksn0w.

The million dollar question, how long before the new iPhone 4 is going to be jailbroken and unlocked? Well we already know that the iPhone Dev Team has already announced that they are going to release an unlock which will work on the 05.12.01 baseband on all iPhones, provided they haven’t upgraded to the latest 05.13 baseband. But since the new iPhone 4 will have the latest baseband, it will be a while before it gets fully jailbroken and unlocked. Another infamous iPhone hacker by the name of Geohot is also said to have a new bootrom exploit, which he has preserved for this new iPhone.

There is a new modified version of PwnageTool floating around in the wild which promises to jailbreak iPhone 3GS on iPhone OS 4 Beta without upgrading the baseband. The creators of the original PwnageTool has confirmed that this version has been modified and redistributed without their permission, and most importantly, it doesn’t patches some important files which are required for the ultrasn0w unlock to work properly.

Apparently, an ex-Apple employee has managed to successfully jailbreak iPhone 3GS on iPhone OS 4 Beta. The redsn0w 0.9.5 jailbreak tool for iPhone OS 4 currently works on iPhone 3G only. The support for other iDevices will naturally follow once Apple releases iPhone OS 4 at WWDC. But KaatjeNL’s jailbreak method works on iPhone 3GS too. And the best thing about it is that it doesn’t upgrade your baseband, which means you can enjoy iPhone OS 4, fully jailbroken on the older baseband with an unlock using ultrasn0w.

Redsn0w has just been updated to beta 4 to support the latest iPhone OS 4 Beta 4 firmware. iPhone OS 4 Beta 4 was released by Apple last week, which since Beta 2 has closed the jailbreak loophole used by Redsn0w 0.9.5b1 and b2 to jailbreak OS 4. But with this latest version of redsn0w, you should be able to jailbreak iPhone OS 4 again on iPhone 3G.

Well it now looks like Geohot is not going to release his jailbreaking bits for the iPhone and iPad anytime soon. According to some of his recent tweets, his tools are not ready for primetime use yet. What this probably means now is that he is not going to release blackra1n for untethered iPhone 3.1.3 jailbreak (as previously thought), iPhone OS 4 and iPad before the next-iPhone is out this summer.

I have just been tipped off on twitter about Limera1n.com – a domain which has been registered by the infamous iPhone hacker named George Hotz (aka geohot). The domain whois record for both blackra1n and limera1n shares same record and confirms that it has been registered by geohot on March 27. Whois record also reveals that it was last updated on April 13, almost effectively the same date when geohot successfully jailbroke iPhone OS 4 which makes it even more authentic. Though there is no confirmation about this by geohot himself.

Most of you must have heard about the thunderst0rm team who claims to have got an exploit+solution to jailbreak and unlock all device (iPhone, iPod and iPad) on iPhone 3.1.3 with 05.12.01 baseband. Today, they have posted a new video which shows the final test build in action. According to them, if everything goes fine, they will release the program Tomorrow.

The hacker/dev behind Sn0wbreeze, F0recast and BlackBreeze has just published a new video which shows off an iPod touch 2G, jailbroken on the newly released iPhone OS 4 Beta. He is said to be working on a bundle for iPod touch 2G and iPhone 3GS, which can be used with PwnageTool to jailbreak the said iPhone and iPod touch on the latest firmware. Video after the jump.

Now that we have a jailbreak (developers only) for iPhone OS 4 Beta, and an upgraded version of Fuzzyband (Baseband downgrader). Technically, iPhone 3G can now be unlocked on the latest iPhone OS 4 Beta, provided that you have one of those rare iPhone 3G’s with 05.08 bootloader that is downgradable to 05.13.03 baseband of OS 4 to 04.26.08 so that ultrasn0w can unlock it.

Similar to the hack which enabled multitasking on iPhone 3G and iPod touch 2G running iPhone OS 4 Beta, the following step by step instructions will help you enable Wallpapers support which like multitasking, was locked down by Apple for the mentioned devices. You will need to be jailbroken on iPhone OS 4.0 before you follow the steps below.

The iPhone Dev-Team is back! They have just released a test version of redsn0w 0.9.5 (Mac only for now) to jailbreak the latest iPhone OS 4 Beta. This release is targeted towards developers only to help them upgrade their existing app on Cydia for this upcoming latest firmware.
