I'm an idiot, please explain Jailbreaking

[daviddcmd]

I understand it won't brick my I4. I have the lasest OS 4.2.1

Is there an online easy way to jailbreak, I don't need to unlock.

When Apple updates the lastest OS will I have to jailbreak again?

Does jailbreaking the phone effect the operation of the phone as a phone?

Any other concerns?

TIA

Jailbreaking allows customization of the iDevice. Cydia an alternative to the App Store also is part of the jailbreak. Cydia offers 3rd party apps that Apple doesn't allow in the App Store.

Yes, every time you upgrade your iPhone you will have to jailbreak again.

Jailbreaking does not effect the iPhone at all.

if you are new to jailbreaking, I suggest you wait until the untethered version comes out. It should be pretty soon.
