iPhone Dev Team提醒用户：Spirit当前须冷静
从某种意义上讲，iPhone Dev Team的越狱工具Spirit的发布，仍然要等到iPad 3G到达用户的手中（别问我什么时候，我也不知道）以后。不过根据此次iPhone Dev Team的官方声明，Spirit的确离发布的日子很近了！该工具仍然使用1.x时代的Userland漏洞，具体的开发和发布由破解小组中的comex来执行。此工具第一次成功越狱iPad是由MuscleNerd在4月3日实现的，也就是iPad首发后不到24小时。
Userland越狱给苹果带来了非常多的麻烦，即便不越狱，漏洞也依然存在并始终困扰着iPhone、iPod touch和iPad等使用iPhone OS（iPhone操作系统）的用户。所以一经发布，苹果必然会再作努力，修复这个漏洞，一个非常明显的例子就是去年夏天暴露的短信漏洞，苹果在不到一天的时间内容就发布固件更新，修复了那个漏洞。同样，一旦Spirit发布，必然会引起苹果再次更新固件，又有多少人中招就不是iPhone Dev Team和小编们可以控制得了的了。
的确，Spirit支持所有设备，如iPhone 3GS、iPod Touch 3G和iPad，但不幸的是除非你备份了SHSH和ECID文件，否则一旦升级，苹果完全有能力阻止你再次降级，你也无法再次使用Spirit越狱了！
请务必牢记，使用Firmware Umbrella来创建一个备份，或者在Cydia作者saurik的服务器上申请一个备份。如果要入手iPad 3G，最好的备份方法还是在本机上使用Firmware Umbrella来申请，因为Saurik的服务器随时都可能会被苹果封闭。还有一些注意事项，请用户在越狱之前务必了解：
-Spirit是完美越狱
-Spirit支持所有型号的正常机器
-Spirit不支持解锁运营商（无法让用户使用苹果官方认可之外的运营商的服务）
-Spirit使用时需要先进行激活或破解
再次强调一定要备份SHSH！comex声明，iPad 3G一天不发布，Spirit就一天不放出！至于iPad 3G什么时候能飞入寻常百姓家，那就得问乔大爷了！

At some point after (don’t ask when!) the iPad 3G is actually in customers’ hands, the first “userland” jailbreak since firmware 1.x will be released by @comex. It’s called “Spirit” and was first demonstrated working on an iPad by @MuscleNerd within 24 hours of the iPad’s release on April 3.
Userland jailbreaks are more troublesome for Apple since they expose security weaknesses that exist even for non-jailbroken owners. As such, Apple is likely to close them soon after they’re made public. One recent example of this is the SMS vulnerability exposed at Blackhat last summer. Apple released new firmware to close that hole within a day.
The Spirit jailbreak is most useful for newer devices: iPhone 3GS, iPod Touch 3G, and the iPads. Unfortunately those devices are the same ones that Apple can prevent you from downgrading unless you’ve got a backup of your personalized SHSH blobs. Unless you’ve backed up your SHSH blobs for vulnerable firmware versions, you’ll lose the ability to use the current Spirit jailbreak if you accidentally upgrade.
Please take the steps now to backup your SHSH blobs. Use either Firmware Umbrella to create a local copy, or go through saurik’s server. If you are getting an iPad 3G, it’s safest to backup your blobs using Firmware Umbrella, in case saurik’s server gets bogged down with requests.
Other things about Spirit that are useful to know:
Spirit is an untethered jailbreak.
Spirit works on all devices. (However, the redsn0w and PwnageTool flows will continue to work on those devices they’ve always worked on)
Spirit does not include a carrier unlock. (Please don’t bug @comex about that)
Spirit requires your device to be activated or hacktivated
Please make sure you have your SHSH blobs backed up! While @comex has indicated he’s not going to release the very minute the iPad 3G is out, there’s no telling what Apple might do anyway.
