i have an iphone 4 on a plan with vodafone and am wanting to sell it and get a new phone. i figure i will probably get more for it once its unlocked and also widens the group of buyers.
i found steps on how to do this on the vodafone website but dont really understand how it will work.
it pretty much said to update and restore with a backup then reset to factory settings. how does this unlock an iphone?
bit worried about trying anything im not sure on as i bricked my last iphone when trying to jailbreak it (which i now know how to do)
