The very first question we have to ask: Do you have SHSH blobs for iOS 5.0.1? No SHSH blobs for that version = no jail break on that version, you'll have to go to iOS 5.1 and do a tethered jail break.
There is a method to upgrade to 5.0.1, NOT 5.1 (No untethered jailbreak yet) without SHSH Blobs. I'm on my iPad at the minute and don't have the guide here. When I get to my PC, I shall send you the link if you wish.
