I have an iPhone 3g with OS 3.0.1, and is unlocked with redsn0w.
i'd like to upgrade to 3.1.x and register my iphone but keep it unlocked (or lockit, update then relock). And id like to keep all of my Cydia and Appstore apps, images, contacts, voice recordings (v.important i dont lose these), music, notes etc.
Is this possible? I've looked around on the net but just got baffled! My friend said to use blackra1n: im not sure what it does.
