At the time of this writing. Evasi0n is the tool recommended to jailbreak untethered iOS 6.0 - 6.1.2 on all devices.
Redsn0w is able to perform a tethered jailbreak on iOS 6.0 - 6.1.3 on selected devices

Downgrade
Downgrading refer to a process of Installing an earlier version of Apple's iOS on a device instead of the most current iOS.
Usually, whenever, a new iOS is released, it becomes impossible to install a previous version of the iOS. However, ways have been designed to make this possible provided SHSH blobs have been saved for that iOS one intends to install.

Downgrade is only possible for pre A5 devices. This means that iPhone 4S and 5  are not possible to downgrade. For example, an iPhone 4 with iOS 6.1.3 installed can be downgraded to iPhone 4 6.1.2 if the SHSH blobs are saved. However, iPhone 4S can't achieve that even if SHSH blobs are saved.
Furthermore, apart from the firmware or iOS downgrade, there is also a downgrade of something called baseband. Just like the iOS downgrade, baseband downgrade is only possible for iPhone 3G and 3GS but not possible for later generation of iDevices.

SHSH Blobs
This is a kind of file saved on all devices whenever an iOS is installed on  the device. Its a kind of signature that  accompanies all iOS that are installed on a device.
This file is also store on Cydia server for those that have a jailbroken device but can also be saved on a computer with the help of softwares like iFaith and TinuUmbrella.
The benefit of having saved SHSH blobs is that it gives certain devices (pre A5 devices only) the ability to downgrade their iOS in the future if they so please even if Apple isn't signing it on their servers anymore.

The recommendation is that one should always save SHSH blobs locally with the help of iFaith and TinyUmbrella just in case there is a need to downgrade iOS.
That is, when you upgrade your iOS, do a saving of the device's SHSH blobs and keep on your computer.


At the time of this writing, it is not recommended to update your iDevice to iOS 6.1.3 if you intend on jailbreaking your device untethered. Furthermore, save your SHSH blobs with the software listed above.

However, if you do not plan to jailbreak your device, feel free to update to the latest iOS version.

More terms would be added to the list. However, it is pertinent to note that proper information is needed before you upgrade to any firmware or attemp to jailbreak any iDevice .

feel free to ask questions on any term you do not understand and any task you are not sure of carrying out.
 

One of the most anticipated tool is that tool that is supposed to jailbreak the iOS 6.1 untethered on all Apple devices.
Contrary to the popular ones we have always had from Chronic Dev-team, this one is coming from the Evad3rs team and the name of the tool is Evasi0n which will be released on Sunday.

However, people could be easily fooled with fake jailbreak tools that promises to jailbreak all iDevices on iOS 6.1 untethered. these fake tools are listed below and you are advised NOT to use them or PAY for any of them as they can render your device unusable or install spyware into your device.
Most importantly, wait patiently for the legitimate jailbreak tool. It is usually free and very stable and legit.

Fake Jailbreak Tools
1. Gull1hack & Blacksn0w V2
These tools by the Gull1hack team have been declared fake by the iPhone Dev-team. The tools was supposedly to jailbreak iPhone and iPod touch devices on the new bootrom untethered.

2. FastRa1n0.5
This particular one says it can jailbreak iOS 5 and later untethered and even charge a whooping $24.99 for it. As far confirmation goes, @comex have said that it is fake and does not work. Consequently, it is fake. Stay away from it.

3. Ghost App
This is yet another jailbreaking tool that promises to jailbreak untethered iOS 5 on all iPhone 3G/3GS/4/4S for $24.99 also. It doesn't even have a demo to try out its functions.
Just like FastRa1n0.5 above, it's not legit, its a fake. Stay away from it

4. Jailbreak
This is got me laughing. It is sold for $9.99 and does nothing. It even featured in the Apple app store at a time ( still wondering how Apple allowed a jailbreak tool in the store anyway). Anyways, it was removed from the store when Apple and Dev-Team found out it was a fake tool.

Unlock iPhone 4S
This tool claim to unlock iPhone 4S on any baseband and also jailbreak untethered. On their website, declaration was made that refund will be made if jailbreak and unlock was unsuccessful. However, no real testimony that it has worked.
The best way to confirm a tool is working is to go to various fora. Here you will hear people are saying about a particular app

THESE ARE LEGITIMATE JAILBREAKING TOOLS
These tools below don't need introduction as they are the most popular legitimate free jailbreaking tool available.

1. Redsn0w
2. Absinthe
3. Sn0wbreeze
4. Evasi0n (particularly for iOS 6.1)

Evasi0n is the most recent of them all which will be released on Sunday 3rd of Feb. 2013 for public download. Created by the evad3rs team (pimskes, pod2j, musclenerd etc).
