Am I able to downgrade my iPhone 5 from iOS 6.1 beta 2 to 6.0?

I have a 64GB White iPhone 5 and foolishly updated it to iOS 6.1 beta 2 and I'm scared I won't be able to jailbreak it when the official jailbreak is released. I have both a 6.0 SHSH blob and 6.0.1 SHSH blob saved. Cydia's servers have my 6.0 SHSH blob and I'm assuming that my SHSH blob for 6.0.1 has been saved through their servers also seeing as I have both files here. Would I be able to downgrade still if I have either of the SHSH files?

You can upgrade or downgrade to any current version of iOS supported by your device. This means you definitely can go to 6.0.1 (as of the time of this answer). If you do have the SHSH information stored for a previously installed iOS version, you can go back to that version too.
