GreenPois0n iOS 4.1 Jailbreak Reported to be released 10/10/10 @ 10:10:10am
Remember, never take the official update through iTunes or you will lose your jailbreak. In addition, the 4.1 update will upgrade your baseband, killing your phone's unlock capabilities.
iPhone dev team member, Joshua Hill, has tweeted the goods (unconfirmed obviously)
on GreenPois0nís launch date. In case you didnít read the title, the jailbreak for iOS 4.1 is coming this Sunday, Oct. 10, at 10:10:10 AM.
We still donít really know anything about this jailbreak and hopefully it actually launches on time.
Download TinyUmbrella to store your SHSH files while Apple is still signing them (currently 4.1 only, so if you haven't saved your 4.0.1 or earlier hashes you won't be able to downgrade), and follow the instructions therein to update to 4.1 without updating your baseband when the time comes.
