Yeah well this is my first iPhone. I'm ready to see the features I can do with it when it's jailbroke. I hope they release it soon lol. And hope I can install it on my phone as I haven't ever done one before
Few things to understand then.
First, welcome to jailbreaking. It lets you use and make your phone the way you think it should be.
Second, realize that when you jailbreak responsibility for the security of your device shifts from Apple to you. Don't add sketchy repos and/or download pirated software. If you do, you deserve what may come your way.
Do your research if you want to install anything more than Eclipse. Cydia has to support devices all the way back to iOS 3 or so. So, not everything you see will be compatible with your device. Installing something that isn't can have bad consequences. Bad as in forcing you to restore and thus lose your jailbreak.
The current jailbreaks are what you call semi-untethered. It means that you can reboot your device without having to be tethered to a computer. But it also means that every time you reboot you have to 're-jailbreak'. There's an app that resides permanently on your device that you run everytime you want to rejailbreak.
The jailbreaks before 9.2 were fully untethered. Hopefully, we will see that again.
When you do finally jailbreak, have fun.
PS. The mods are likely to move this thread in to the actual jailbreak forum so don't be surprised.
