Meaning I don't have to get the semitethered package from Cydia, redsn0w applies it automatically while jailbreaking?
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).
That is normal behavior. Most tethered units will physically reboot, but Cydia, MobileSafari and other hacks will not launch.
Your phone basically reboots in a non-JB state.
Hm - I always heard that tethered JBs caused you to get stuck at the apple logo when you attempted to boot up normally.
Your comment makes me wonder what the point of the semi tethered tweak is - sounds like the same functionality you describe above. Thanks for the insight though.
The POINT of the semi tether is that if you are away from a computer and your phone crashes/reboots/whatever then you will still be able to use things like safari and other things that may require that special boot from redsnow.
