Let me clear this up straight. No, the phone you see in the screenshot is not a jailbroken iPhone 4, but rather a jailbroken iPhone 3GS, running iOS 4. The iMovie app you see is basically a “broken” port which was being tried to run on non-iPhone 4 devices but had issues in the end.
If you have an iPhone 3G and you have this feeling that upgrading to iOS 4 has slowed down your device and that you want to go back to iPhone 3.1.3 / 3.1.2. Or if you are one of those iPhone 3GS (new bootrom) or iPod touch 3G / 2G (MC model) user who has upgraded to iOS 4 only to find out that you cant jailbreak it can follow the instructions posted below to downgrade iOS 4.0 to iOS (formerly iPhone 3.1.3 or 3.1.2).
The official ultrasn0w unlock is now available for iOS 4 which works on all basebands including 05.13.04 and 05.12.01 on iPhone 3GS and iPhone 3G. Since there is no jailbreak available yet for iPhone 3GS with new bootrom, you cant unlock it as even though the baseband is unlockable. This is because unlock relies on jailbreak. So if you have an iPhone 3GS with new bootrom and you rely on an unlock, it is best to avoid iOS 4 (formerly iPhone OS 4) for now.
You can keep on talking about desktops era being over, iPads and tablets killing Windows based netbooks and notebooks, but you cant deny the fact that Windows 7 is by far the fastest selling OS in the history! and it runs on majority of the notebooks/netbooks and desktop PCs near you.
Some users were complaining about newly released iBooks for iPhone having issues on jailbroken iOS 4 devices. The good news is that Redsn0w has been updated to version 0.9.5b5-4 in order to fix this problem. The official change log is as follows.
iH8sn0w’s Sn0wbreeze 1.6 is almost ready for primetime use. He will release it in a day or two. For those of you who don't know, Sn0wbreeze 1.6 is by the same developer who is behind other popular iPhone jailbreak tools such as sn0wbreeze for iPhone 3.1.3, f0recast and BlackBreeze.
TinyUmbrella has been updated to support the new iOS 4 on iPhone 3GS and iPod touch 2G/3G. iPad is also supported but iOS 4 for iPad isn't available yet. iPhone 3G is not supported because you don't need to save SHSH blobs for iPhone 3G, and older iPod touch (non MC model).
Redsn0w has been updated to bring jailbreak support for the newly released final version of iOS 4 for iPhone 3G and iPod touch 2G. Available for both Windows and Mac, redsn0w jailbreak tool additionally also enables options for multitasking and background wallpapers on iPhone 3G and iPod touch 2G which otherwise are disabled by Apple.
The response that Apple has got for the new iPhone 4 has far outstretched their supply chain. Apple today has issued a statement in which they have stated that more than 600,000 iPhone 4s have been pre-ordered through Apple and its carrier partners yesterday. According to reps at AT&T, this is ten times as many orders as they took for the iPhone 3GS last year.
The official ultrasn0w unlock has been released by iPhone Dev Team for iPhone 3GS, with older bootrom running 04.26.08 baseband on iOS 4.0 (formerly iPhone OS 4). For those of you who preserved their baseband by jailbreaking iPhone 3GS on iOS 4 using PwnageTool can now unlock, provided that your phone is running the older 04.26.08 baseband.
