What are you trying to do? You are trying to reset all settings by erase doesn't that erase everything on the phone including the firmware?

I was just trying it out. No it just makes the phone like day one when booted for the first time. But my iPhone did not boot

coz jailbreaking is a process of erasing all your phone features completly.

Sorry, I don't believe that's what jailbreaking is about, or does. I certainly have all the features prior to jailbraeking. Granted, I haven't tried what the OP is asking. But, I don't see a reason to. If I want it back to "out of the box", I'll connect it to iTunes and do a Restore. I'm not 100% sure the Reset in the settings will take it back to factory.

Once you jailbreak, you can't use the "Erase All Content and Settings" option. I think the last time I tried it it froze booting up.

So you if want to start over, you'll have to restore, and then re-jailbreak. Or you could also restore using a custom ipsw from pwnage tool or sn0wbreeze.
