Crap, can't find an exact clear answer.. but, say I'm giving away my iPhone 3GS (16gb if it matters), currently on 4.0, 5.13.04 bb, what's the best way to reset all the information without bringing the baseband up?
The phone will need to be unlocked as well.
I have read through this:
redmond pie link but it warned something about an unlock..
(Using a mac, if it helps!) Thanks in advance guys/gals.
