I think I get why OP is asking... I'm on the tethered 5.1 JB, & I have installed several Cydia apps. When I've been required to reboot, I have yet to get stuck on the apple logo.
The phone will boot to my springboard, but JB apps are gone, & Cydia & Safari crash on launch just like the Corona semi-tethered tweak. I then power the phone down like normal & enter pwnd DFU, instead of going to Pwnd DFU from the apple logo.
I have no idea why this happens - may e it's just because I don't have a ton of tweaks/apps installed (Winterboard, iFile, & Gridlock at the moment).
