Here's something I've never quite understood. 
Once I've successfully jailbroken an iPhone with PwnageTool, if a newer version of PwnageTool appears (but no newer iOS yet appeared) should I re-jalbreak or is this not necessary?
...or is the rule just to always update/jailbreak iOS 5.x.y with the equivalent PwnageTool version (5.x.y)?
Thanks!
