Yes you read that right! iPhone 4 has been unlocked successfully! Planetbeing (who ported Android on iPhone) has managed to unlock iPhone 4 running on iOS 4 and posted about this news on his Twitter account.
With an unlocked iPhone, users in US can easily use prepaid SIM cards other than AT&T and comes handy when you plan to travel outside US and still want to use the iPhone. Planetbeing has posted teaser image of iPhone 4 running on Bell carrier.
