A few minutes ago Geohot posted on the account or from Twitter a picture with iPhone OS 4.0 cu blackra1n and application Cydia installed, is the second proof that iPhone OS 4.0 it can be jailbreak-look, before purchasing, coming from MuscleNerd which unlike Geohot made a video lesson.
So, not even 4 days from availability iPhone OS 4.0 there are already 2 solutions for jailbreak, but I personally don't think that any of them will be released before the official release of iPhone OS 4.0 since summer, anyway we know for sure that iPhone OS 4.0 it can be broken.
I know that most of them are waiting for a jailbreak solution for 3.1.3 firmware, but if geohot started playing with iPhone OS 4.0 then he's probably done with blackra1n for iPad si 3.1.3 firmware and could release the solution soon!
