Ok guys.. Mac version of the guide is now up! (Windows version can be found here) The requirements though as mentioned earlier remains the same. You will need a iPhone 3GS (with new bootrom) on iOS 4, which has SHSH blobs saved for iPhone 3.1.2. Some other important notes about the jailbreak are as follows.
iH8sn0w – the developer behind popular iPhone jailbreak tools such as sn0wbreeze for iPhone 3.1.3 / 4.0, f0recast and BlackBreeze has just written a detailed tutorial on how to jailbreak iPhone 3GS (with new bootrom) on iOS 4. But as I mentioned earlier, there is a little catch to it. 1) it is a tethered jailbreak (whenever you turn off your phone, you will need to re-connect it to a computer to be able to turn it back on) and 2) it will only work for those devices which have their SHSH blobs (ECID SHSH) files for 3.1.2 (NOT 3.1.3) saved on Cydia.
When iOS 4 jailbreak first came out, it was only compatible with iPhone 3GS (old bootrom), iPhone 3G and iPod touch 2G (non-MC models). Things were even more trickier for iPhone 3GS. These 3GS devices were not only required to have old bootrom, but they were also required to have previously been pwned or jailbroken on anything (like blackra1n) other than Spirit.
The new Game Center which was available for testing purposes on pre-release GM version of iOS 4 was removed from the final public build which was released on June 21st. This was because Game Center was not ready for primetime use and so Apple rightly removed it from the final build. If you saved the Game Center files from iOS 4 GM build, you now can get it installed again on your jailbroken iOS 4 device.
There is a new video going around in the wild which shows iPhone 3GS (with new bootrom) on iOS 4 jaibroken using an upcoming version of Sn0wbreeze. This video has been confirmed by iH8sn0w - the developer behind popular iPhone jailbreak tools such as sn0wbreeze for iPhone 3.1.3 / 4.0, f0recast and BlackBreeze as legit.
Apple today in an open letter has officially acknowledged the iPhone 4 reception problem, which is confirmed as a software issue which will be fixed via software update coming in the next few weeks. The problem as it turned out was related to the “totally wrong” formula which was used to calculate the signal strength.
Foursquare has just rolled out version 1.9.0 for iPhone and iPod touch which brings iOS 4 and iPhone 4 support. This new version brings a new map view where you can see all your friends, high-res graphics which are optimized for iPhone 4 Retina Display, performance improvements and bug fixes.
Well its here finally! I got my iPhone 4 shipped here the other day and needless to say, the experience so far has been nothing short of spectacular. It’s a factory unlocked version which I got from UK. What this means is that I can use it with any carrier I like, unlike the US version which is tied to AT&T contract.
Sn0wbreeze 1.6.2 has just been released. This new update brings fixes for YouTube, iBooks and iTunes Error 2 which has been problematic for most users after iOS 4 jailbreak. Apart from this, this new version also brings support old bootrom Spirit jailbreak tool users who can now jailbreak their device on iOS 4 with Sn0wbreeze.
