越獄步驟不用我啰嗦了，需要的下吧。超級雪ultrasnow也升級到1.2.3了，不過同樣不支持新baseband，詳細信息請看官留意下面文字吧5ht紅軟基地
Today’s PwnageTool and redsn0w incorporate @i0n1c’s port to 4.3.3 (it’s ironic that such a long-lasting untether doesn’t even have an official name!). It also of course uses geohot’s limera1n bootrom exploit to inject the jailbreak. The 4.3.3 untether works on all devices that actually support 4.3.3 except for the iPad2:5ht紅軟基地

Some things to note:5ht紅軟基地
ultrasn0w unlockers must stay away from redsn0w! Use only a custom IPSW to update to 4.3.3， to avoid updating your baseband. There are plenty of tutorials for both redsn0w and PwnageTool at sites like iClarified.com. Or feel free to ask away in our comments section below.5ht紅軟基地
ultrasn0w has been updated to v1.2.3 to be compatible with iOS 4.3.3 and earlier (the ultrasn0w update does not include any new baseband support!). Please reboot your iPhone using the normal “slide to power off” swipe after installing ultrasn0w 1.2.3.5ht紅軟基地
By popular demand， redsn0w now allows you to enable multitasking gestures (although most will find it useful only on iPads).5ht紅軟基地
iPad2 update: The iPad2 jailbreak remains under development. As you may know， the original exploit @comex developed in the first week of the iPad2 release was mysteriously fixed by Apple within days of its development. Partly because of this， don’t expect much public discussion of the iPad2 jailbreak until it’s actually finished and ready for release (and please avoid asking about it). In all liklihood， it will be a userland exploit like the first (unreleased) one， not dependent on bootrom dumps. The first one can’t be released even for those with the original 4.3 firmware due to legal (distribution) reasons.5ht紅軟基地
