Jailbreak & Unlock tutorials and FAQ from iphoneroot

UPDATE: Apple latest firmware is iOS 5.1.1. Apple has stopped signing all other firmwares, including iOS 5.0.1, iOS 4.3.3 and iOS 4.3.5. This means you can NOT restore to 5.0.1/4.3.3/4.3.5 any more (both original and custom), unless you have saved your SHSH keys for it.

If you have decided to perform an untethered jailbreak and unlock, you need to get the following information:

1. What type of device do you have (iPhone 3G/3GS/4, iPod Touch 3G/4G, iPad 1/2, Apple TV)?
2. Do you need unlock (if your iPhone locked to one carrier and you want to use it with another)?
   The answer is NO, if the device is not iPhone, if it was purchased as factory unlocked and can be used with any cellular carrier (f.e. in Canada, France, etc).
   If the answer is YES, you need to find out your modem version (Setting-General-About-Modem).
3. What firmware version do you have? Take a look at Setting-General-About-Version. For example it could be iOS 4.3.3.
4. What operating system do you use on your desktop (Windows, Mac OS)?
