According to the latest news , New Turbo Sim based unlock for iPhone 4 would be coming after Chinese New Year i.e after 23rd January - 2012.
This would come as huge relief for some of us, who are stuck with 4.11.08 baseband on iPhone 4.
Hopefully this would be true and not just rumor. Waiting for Chinese New Year to bring some good news to us iGeeks!!!
