Choose the right software to jailbreak an iPhone

You now have several choices on how to jailbreak an iPhone. The question now is whether you want to upgrade you iOS to the latest version, and for whatever reason retain an older iOS version. Depending on the iOS version as well as your iPhone model, there are several ways to jailbreak an iPhone.

Jailbreak an iPhone if you don't need to unlock

As posted in other pages on this site, if you jailbreak an iPhone, you need to first find out if you have an unlock available for the baseband that you will have to upgrade to. If you depend on a carrier unlock, avoid upgrading your iOS unless you're sure there is an unlock for it as well. The following ways to jailbreak an iPhone almost invariably requires an upgrade of the iOS, and for Redsn0w for example, there is no unlock for the 4.3.3 stock upgrade. If ever, you will need a custom iPSW to upgrade your iOS to avoid modifying your baseband to an unlockable level.
