I have tried a couple of times to install the new baseband on an iPhone 4 with 4.2.1, I follow the tutorial, but the option to install the iPad baseband never comes up for me when it should. Anyone know what I might be doing wrong?
To unlock the iPhone. However, Phenith, I would wait until 4.3 comes out. Pretty sure there will be an unlock for it. If you update to the iPad baseband, there is no going back even if you restore your phone. If you were to have any problems and need to bring it to Apple, they will know the phone was JB'd and will not help you at all. The iPad baseband is 6.x and iPhones are only at 4.2.1.
