I bought a used iPhone 2G for my friend. Currently the iPhone is unactivated and is telling me to connect to iTunes. How do I figure out what iPhone f/w I have? Also how do I unlock and JB a unactivated iPhone.
Here you go. Follow this link. Not giving more info like Mac/PC would have helped.
This is a tree menu, follow what applies to you and then click on it. All info and instructions will be there. Enjoy
