Restore to Factory Default
I am sure this has been covered at some state, but despite having searched, I can't find the information:
What I want to know is, if I purchase an 1.1.2 iphone, jail break etc..., is it possible to restore the device to factory defaults at a later date.
I have seen references to restore and to virginize, but am some what confused. Is there a glossary of terms commonly used so that others could consult before they need to ask a similar question to which I am asking.
Please folks don't Flame me for this, but if you do I will understand.
