i did not upgrade to 4.4 + and realized kinda late that I can't use mirroring on my ipad2..as I'm on 4.3. Since i've jailbroken and enjoying xbmc,plex and what not's ...what are my options besides going straight 5.0 or 5.01 which is a tethered jailbreak

Any way to upgrade to 4.4 without the SHSH blobs for them.? i have a backup of my 4.3 blobs..

Or anyone got any updates on when a untethered jailbreak for 5.0 will be out? Should i go to 5.0 just so that i can get the SHSH blobs? is apple still signing 5.0?
