WARNING: Don't Install iTunes 9.2 If Planning to Use Spirit Jailbreak

The iPhone Dev-Team has warned users not to install iTunes 9.2 if they plan on using Spirit for a fresh jailbreak.

Don't install today's iTunes 9.2 if you plan on using Spirit for fresh JB (but it's fine for PwnageTool & redsn0w users)

The iTunes 9.2 update adds compatibility with iOS 4.0.
