removing itunes account info from jailbroken iphone?
i recently jailbroke my phone to sell it on ebay, but today when i went to download a free game for something to do, i got asked for my itunes account password, the phone still remembers my username still on it, which i don't want to leave on a phone i'm about to sell. how do i remove that from the iphone? do i have to do a complete resetting of all data and settings, and if i have to do that, will i have to rejailbreak the iphone again or will the resetting not effect the unlocked and jailbroken aspect of it?
btw i have a 1st gen iphone jailbroken at 2.1 if it helps any.
