You would have to update to iOS 5.1
5.0.x isn't being signed anymore.
For the iPhone 4, the jailbreak is tethered via Redsn0w. http://blog.iphone-dev.org/
If you have 5.0.1 blobs for your i4 you can upgrade to that and jb untethered.
Ok, last dumb question... I always realize how dumb I am when I start thinking about jailbreaking my device!
With my current setup, if I just run the update from itunes and installed the latest version of 5.1 then I can use the redsnow tethered jailbreak, without anything else needed?
