If you’re into jailbreaking your iDevice or have ever wanted to, Spirit will allow you to do it regardless of what OS you are using as long as you aren’t using your device with another carrier. Meaning, if you currently have a jailbroken phone and are using T-Mobile’s network, you can’t use Spirit to jailbreak your device without losing your T-Mobile service. This is one of the first jailbreaking apps that is truly easy for the layman to use. That being said, try to remember and follow the directions before going forward with the hack.
There are a multitude of reasons one may wish to jailbreak their iDevice. The best reason is that you can have a lot of that fancy OS 4 functionality before OS 4 publically arrives. Things like multitasking and utilizing program folders are easy add-ons on a jailbroken device.
If you do jailbreak your device going forward, be careful when doing any type of updates. Apple has been known to specifically include code that kills jailbreaks. This is almost always true for any new firmware release but occasionally a new iTunes update will cause problems for jailbreakers as well. In any case, many of the reasons people jailbreak their devices will soon case to exist due to the impending release of OS 4.0 by Apple. Below is the program’s information which has been harvested from Spirit’s release website – spiritjb.com
Spirit is an untethered jailbreak for iPad, iPhone, and iPod touch on the latest firmwares.
Spirit is not a carrier unlock.
If you currently are using a tethered jailbreak, you have to restore to use Spirit. Do not upgrade if you use an unlock on an iPhone 3G or 3GS. (You can, however, restore to 3.1.2 if you have SHSH blobs for that version.)
(If you mistakenly ran Spirit despite using a tethered jailbreak, try these instructions.)
Any iPad, iPhone, or iPod touch on firmware 3.1.2, 3.1.3, or 3.2.
An activated device: one not stuck on the Connect to iTunes or Emergency Call screen.
Any version of iTunes 9 (including 9.1.1).
Syncing with iTunes before trying this is highly recommended.
Note: On iPad, all this is still sort of beta. Some packages in Cydia, not designed for iPad, might screw up your system and require you to restore. Be careful. (And no, Cydia’s appearance is not final.)
