@F_Li: That's what the little X button next to people's posts is for.

I just want to point out that this uses the same exploit as #limera1n, which came out 2 days ago.

@Kamatari +: Hum, basically, greenpois0n was going to use a different exploit, but then #geohot came out of nowhere with limera1n, so greenpois0n just switched to the limera1n exploit so that no exploits were "wasted".

Hum-hum? What about Backgrounder?

@bantu89: FaceTime over 3G, theming via WinterBoard, SBSettings, etc.

@sahilm: If you just get a purple screen, it means that the servers are overtaxed (they're being hit by too many people at a time). Try again, it should work now.

FaceTime over 3G!

@yo2boy: I jailbroke my iPod touch running iOS 4.0 without a problem.

If you're already jailbroken, you can protect yourself against similar exploits by installing "PDF Loading Warner" from BigBoss' repo.

@Limbero: If you're already jailbroken, you can protect yourself against similar exploits by installing "PDF Loading Warner" from BigBoss' repo.

@Travis Tedford: If you really screw up your device, restore and then re-jailbreak. Don't re-jailbreak on a device that's already jailbroken (restoring will wipe the jailbreak).

@TomXP411: The exploit is a font bug in a PDF.

@NuevoLeon: ...and the #Cydia Store, too.

@coreynyc: Reboot, then try to jailbreak again.

@thenail: You can either buy it from the Cydia Store, buy it from the RockYourPhone Store or install a cracked version.

iPhone 4 Jailbreak Now Available: One Click, No Computer Required

Here is some info:

@fo_shizzle: No, jailbreaking gives you root access to your phone and unlocking lets you use your phone with any carrier. According to @planetbeing, the iPhone Dev Team's iPhone 4 unlock will be released within the next 48 hours.

@milkisgood: I'd install WinterBoard (a theming utility), SBSettings (an all-purpose settings app that can be accessed without leaving the current app) and some Wi-Fi faking utility (there are many available; that way, you can use FaceTime over 3G) to start off.

You can also enable this by downloading some free Wi-Fi faking utility.
