Download greenpois0n RC6.1

On February 18, 2011

Chronic Dev-Team recently updated the greenpois0n jailbreak tool to RC6.1 and includes patch for iBook fix. Most greenpois0n Jailbreakers, who attempted to open ebooks purchased from the iBook store were prompted with an error message: There is a problem with the
configuration of your iPhone. Please restore with iTunes and reinstall iBooks.
Of course it will remove the jailbreak if you restore your device with iTunes.

iPhone Dev-team has updated PwnageTool 4.2 and iH8sn0w has updated sn0wbreeze 2.2 to fix the iBooks issue on iOS 4.2.1.
