Are you a part of the jailbreaking community? Although Apple has tried their best to put an end to jailbreaking devices, a new jailbreak has surfaced for iOS 4.3.1 device such as ipad and iphone4 unlocked that will make that community happy. Up until now, the jailbreak has not been ideal because it would be undone anytime that handset was reset or turned off. This pretty much made it not worth the time of the user, but now it appears that a new jailbreak method may fix this problem.
The new tool, titled redsn0w, will be able to jailbreak iOS 4.3.1 devices, and they will remain jailbroken even after they have been shut off. Of course, as with any jailbreak or hack, you have to use it at your own risk. This practice is not condoned by Apple, and they will refuse to support you with any issues that come as a result of a jailbreak.
Make sure that you know what you are doing and have read enough information on the subject before attempting the jail break - especially if your phone is not currently under warranty. Make sure that if you attempt to unlock your handset to use with another carrier that you are not using 4.3.1, because there are no jailbreaks for that device that are working at this current time.
There is already quite a number of articles that are out there and will help you to quickly and conveniently jailbreak your iOS 4.3.1 device like unlocked iphone 4, ipad and ipod. So make sure to read through them before making any serious attempts. It is in your best interest to be more cautious, especially since this jailbreak was just released and the ramifications and issues with it are not currently clear that this time. Also, look for user testimonials for your specific model of device before moving forward so that you can better troubleshoot any issues that you may have.
