This is my first post. I have been reading posts for several weeks. I have seen posts regarding the restoral of the original firmware but I am unclear as to the status of this process.

I bought a new iPhone yesterday. I am considering the hack until I can get out of my Verizon contracts. I have an ATT Phone for work and want to use that SIM for now. I want to restore the phone to the factory settings in a few months when I can unload verizon. Will I be able to restore the phone If I choose to in the future, without significant difficulty? I have not opened the box yet and don't know which firmware version I have, also I do not have a Mac.

Thanks for your patience and help.
