Just a minute ago, @MuscleNerd a core member of the iPhone Dev Team released an updated version of RedSn0w 0.9.6rc10 Untethered Jailbreak for iOS 4.3.1.
This updated version brings boot animation (This feature was also added in Sn0wbreeze 2.5.1 for Windows) & enhancements.
For who have already jailbroken their iOS device using RedSn0w 0.9.6rc9 can run the latest version of RedSn0w 0.9.6rc10 on top it and select Boot Animation. But, keep in mind to dis select Cydia to avoid package conflicts.
Once jailbroken, Launch Cydia and Install Animate from cydia.machackpc.com. That’s it!
Those running redsn0w may have noticed we enabled too many Settings options in some versions of the jailbreak (for instance, what you want your side switch to do, even if you have no side switch because you’re not using an iPad). Release rc10 of redsn0w corrects that (you can just run it over your existing jailbreak…be sure to de-select Cydia to avoid package conflicts).via[MacHackPc]
Along the way, we’ve also added the option to enable boot animations…these animations can be installed via Cydia, but be sure to select which animation to use via the Settings->Bootlogo setting after you’ve downloaded an animation (and again, you can just run rc10 over your existing jailbreak…be sure to de-select Cydia to avoid package conflicts).
