Within days after US copyright watchdog made jailbreaking public, a jailbreak solution for iPhone 4 was launched that can be done through your iPhone handsets instead of your PC or laptop as it used to be the case till now.
After some legalities in the past years Jailbreakme was shut down but with the exemption of the congress regarding the DMCA ruling, hacking the iPhone is a legal procedure now. So the time that iPhone jailbreaking is safe and sound , Jailbreakme is now back on track along with the release of the new iPhone 4 jailbreak.
Meanwhile jailbreakMe.com seems to be getting very heavy traffic from people interested in getting their phones open and be able to use it on whichever telecom network they want to use. In the US, unlike many other countries, iPhone users cannot change their telecom operator and the single entity that provides iPhone services is AT&T.
As of now you can still visit Jailbreakme but be sure that you synced first your iPhone or iPod touch. While reading some updates from Engadget for the Jailbreakme downtime, it seems Saurik upgraded the server that handles the said jailbreak added to that many reports or tweets that their phone got bricked after updating and yet other owners successful JBed their iPhone.
