If someone has an unlocked, jailbroken phone, what will happen if the update button is clicked in iTunes? Will the phone be updated and work? My friend wants to do that.
I did the same a month ago when my friend gave me the iPhone and everything worked well. His phone was also unlocked and jailbroken, but, after the update, I wasn't required to do any of the stuff. My phone is working well and I am able to download and purchase apps from the App Store.
Should I proceed with updating my friend's phone too?
