I have an iPhone 3G on AT&T, I could careless if it is or isn't unlockable, because it is activated. I am very intrigued with what OS 4 has to offer and to be released soon I am thinking about restoring to 3.1.3 along with upgrading my baseband to 5.12. I really don't need the jailbreak because once background image is available I wont need Winterboard, I wont need OpenSSH to restore anything and considering the fact that I barely take videos I dont need CyCorder but is it worth keeping the jailbreak and the occasionally buggy software.
