Interview by the Dev team:
Question: When is the iPhone 4 Jailbreak and Unlock is going to be released?
Comex: You will have to ask Saurik if he’s done with that bootstrap yet. Like I hate to say this because people will be complaining, but it is pretty close to done.
PlanetBeing: Unlock is done. Just waiting for the jailbreak to be released.
Chpwn: The jailbreak definitely needs a lot of testing before it is released, to make sure it works on everybody’s phone, and that there are no issues like Spirit had where it deleted all of your photos in the first few days of the release.
