MuscleNerd, infamous member of iPhone Dev-Team, informs us through a new tweet that he is working on iPhone 4 baseband unlock. Please note that the iPhone 4 sold in US and some other non European counries are sim-locked and therefore can not be used with any SIM but only with the operator of the country where it was purchased.
Other side planetbeing is also working with Musclenerd, Planetbeing is also very well known in the iPhone hacking scene. According to information released, Apple changed some things (in the new baseband) making it unusable with blacksn0w. We will keep you updated with al the latest.
