I have a 3GS. I jailbroke it some time ago. I decided that I wanted to restore it to its factory settings and run with a clean system.

I then selected the option to delete all content (I think under General Settings).

Now, the phone won't boot up. It just hangs when the logo appears. (Well, the jailbroken logo of the skull.)

How can I fix this?

It's a very well know issue not to hit reset all settings when jailbroken.

Hold power and home together until phone restart, if that doesn't work put phone in DFU-mode and restore to stock, which is actually the only way to fully unjailbreak

I've held power and Home and restarted a few times, and it keeps locking. How do you put phone into DFU-mode?

No why would you think it's a joke?

I'm new to Apple, so excuse my ignorance. I read that it stands for "Definitely ****ed Up mode", which makes me think it's not for real.

Or am I wrong?

Download iTunes. I don't know how else you could do it sorry.

I'm running Ubuntu. I'll have to wait until I buy a Mac before fixing my phone, or use a friend's Mac.

This might be the best hidden meaning behind DFU mode. That's the only times I have really used it.

Or, you know, any time you want to jailbreak (for many jailbreak methods, anyway), save blobs using RedSn0w, upgrade to a custom firmware, or basically anything that isn't a straight iTunes restore/update...
