The iPhone dev team released a teaser video on Sunday hinting that they are closer than ever to unlocking the iPhone 3G. The video shows a custom application running on the PMB8878 baseband processor. They successfully connected to the baseband, used a custom AT command to launch their baseband application and voila they return a list of all the tasks running on the Nucleus OS. Now that they can inject and execute code in the baseband, full unlocking is right around the corner. Carrier independence here we come!
