Limera1n exploit used on all currrent jailbreak tools (Limera1n, Redsn0w, Sn0wbreeze, PwnageTool and Greenpois0n) to jailbreak iOS devices running iOS 4.1 upto iOS 4.3.2. For who don’t know, Limera1n is hardware exploit, so that all hackers expected to see it patched in the newly white iPhone 4. Thanks Apple for didn’t patching Limera1n exploit.
Conclusion, jailbreak white iPhone 4 is easy to developed with the current jailbreak tools, so releasing looks imminint 😉 . Stay tunes.
