I know you know this but there are hundreds of iPhone, iPad and iPod users joining the jailbreak community on daily basis therefore I thought to write this short post to just give precise overview of common terms:
Difference between Tethered, Untethered and SemiTethered Jailbreak
Tethered Jailbreak – A tethered jailbreak means that each time you reboot your iDevice, the boot process will fail (you’ll get stuck on the Apple logo). To get around this you will need to plug your iDevice back into your computer and re-run the jailbreaking tool like Redsn0w and select “Justboot tethered”.
Untethered Jailbreak– An untethered jailbreak means that your iPhone, iPod Touch or iPad will function as normal as it was before jailbreak.
SemiTethered Jailbreak – SemiTethered Jailbreak means that you still have a Tethered Jailbreak but if you want to reboot your iPhone, iPod Touch or iPad, it will re-boot into a semi-functioning state where you can use apps such as Phone/SMS etc but not Cydia and Safari. To work with jailbroken apps you need to reboot tethered by using the jailbreak tool.
Difference between Stock firmware and Custom firmware
iOS Stock firmware – This firmware officially come from apple and may or may not update your iDevice baseband automatically.
iOS Custom firmware – This firmware do not include baseband on it. So you don’t have to worry by getting your baseband change/update. This is only possible by excluding the baseband using redsn0w or sn0wbreeze jailbreaking tools by selecting stock firmware to make a new custom firmware.
Difference Between Unlock and Jailbreak
Jailbreak – Allows you to install 3rd party applications, customize graphics, sounds, etc.
Unlock – Allows you to use the phone on networks other than AT&T or the one to whom you registered.

Please note: This is a tethered jailbreak this means that you need computer every time you boot your idevice. And before using your device you will have to run Redsn0w again.
