Charlie Millers and Collin Mulliners claimed that they can control any iPhone by sending a special SMS, however iPhone OS 3.0.1 firmware fixes this iPhone SMS vulnerability which could allow any hacker to remotely access all the data on your iPhone by just sending you a text message. So we strongly recommend you to update your iPhone OS 3.0 to OS 3.0.1 to save yourself from the SMS bug.
Yes iPhone OS 3.0.1 Firmware is compatible with Redsn0w because the difference between OS 3.0.1 and OS 3.0 is that in OS 3.0.1 only SMS bug was fixed. RedSn0w which never touched SMS vulnerability and only targeted the core functionalities to jailbreak keeps you iPhone compatible with the latest OS update.
Update : Unlock iPhone Firmware 3.1 Compatible With PwnageTool 3.1

The Dev Team releases patch as soon as any OS upadate is released by Apple but this time they have not released any patch because they don't need to, since this update is already compatible with Redsn0w.
Just upgrade to iPhone OS 3.0.1 and simply point RedSn0w v0.8 to the OS 3.0 IPSW and it will continue working!
iPhone OS 3.0.1 Firmware can be downloaded from iTunes.
