i got the old iphone3g that does not support the current ios5, its on ios4.2.1 (8c148, what ever it means)
someone is interested in buying it and i am tempted to sell it and get the new iPhone 4s earlier than january when my contract expires. what i want to know is how do i de register my iPhone 3g in order to sell it. i know in setting >general there is a reset button, never used it but is it enough. i want to remove every app, emails, txt msg and phone numbers so the new buyers starts from scratch. how do i do it? Thanks
on a side note, non of the 6 orange phones shop i visited have the 4s in stock, if i order it then it will take 2 weeks or more for delivery
another this is, if an iPhone is jail breaked, is it then unlocked to use any sim card for mobile phone?
