While there is now a jailbreak for iOS 4 and an unlock for the iPhone 3G and 3GS, there is still no unlock for the iPhone 4. In a tweet sent earlier today, MuscleNerd said the Dev Team will push back the release of the iPhone 4 unlock for a short period, just the time for them to test it out a little bit more.

If I had a guess, I’d say the iPhone 4 unlock will come in the next few days, so don’t go anywhere, I’ll keep you posted!
