Even though we lose the jailbreak it’s still possible to rejailbreak with redsn0w right?
dude just dont update, chill for like a week and wait for jb tools…
if you have tour shsh blobs saved then you can update and later downgrade, but whats the point if youre not jailbroken or anything? imo just wait…
by the way, this likely updates your baseband, so if you’re an unlocker, stay the fuck away!!! you dont know if we’ll get an unlock soon, if at all… in such case, i’d wait for an update that preserves your baseband (pwnagetool) and that will be when a jailbreak is released…
Did you not understand me? I asked of redsn0w could rejailbreak you after you update…
