Welcome!* Glad I caught your comment on @richgaynor's post. Following you now

*edit: Oh yeah, I thought I recognized the photo of that bomber, I think I followed you before on your old account. Anyway, welcome back. Glad your old account isn't a total loss as it seems your phone has your active key on it, if you can start a power down and make transfers.

If the Keychain app has the active key it may also have the posting key and both might be able to be viewed/exported like castleberry mentioned.
