iPhone Dev Team Says Don’t Update To iTunes 8.2 If You Plan To Jailbreak
June 2, 2009

It breaks your ability to use QuickPwn, PwnageTool, and iPhone Tunneling Suite (ssh over usb). We don’t think this is a deliberate breakage of these tools. It’s just that Apple has updated a low-level USB protocol that normally only Apple cares about (but jailbreakers care about).The Dev-Team states that since this isn't a deliberate anti-jailbreak measure, it should be easy to fix. They don't, however, intend to issue a fix until 3.0 is out, so you will just have to wait patiently. [Thanks to Odie for supplying the image!]
