Yes! This is TRUE! The new iOS 4 released about 5 hours ago, has been Jailbroken already and i am running a Jailbroken iPod touch 2G with Multitasking and Home Screen Wallpapers!
iOS 4 has been Jailbreaked!!!
Redsn0w Beta 5, 1 is working with iOS 4 (Official). When it asks for the .IPSW file, just feed in the ORIGINAL GOLDEN MASTER (GM) .IPSW file. It will continue to Jailbreak your Device and enable Multitasking and Homescreen Wallpapers!
While using Redsn0w 0.9.5 Beta 5,2, it crashed in between the Procedure.
Therefore, i was unable to activate Battery Percentage!
Some people are facing problems with “iBooks App for iPhone” after using RedSn0w Beta, including myself.
All that you need to do, is download the latest (Redsn0w 0.9.5 Beta 5,4) and run it again. JUST UN-TICK THE ‘CYDIA’ OPTION. And you’re done!
Other Alternatives such as Sn0wbreeze and PwnageTool (Mac Only) are also out.
Redsn0w 0.9.5 Betas ONLY WORKS WITH iPhone 3G and iPod touch 2G.
(Basically for enabling Multitasking and Home Screen Wallpapers).
