    My son just upgraded to an iPhone 4S. He sold his iP4. I want to make sure we erase his data, including the iMessage. I have read nightmares of others getting the original owners iMessages. The old phone is no longer activated on any cell network.

    How to I zip out ALL info form the phone?

    Thanks

    Go to: Settings -> General -> Reset -> Erase All Content and Settings.

    This however can probably only be done with a (micro) sim card in the phone.

    A better option is restoring to new in itunes.

    Resetting through settings will bring the phone back to its original state when it was bought. I've erased and sold all of my iPhones this way and never had any issue whatsoever.

    Waste of time! And if the iPhone is jailbroken, you'll need to restore in iTunes anyway..
    Instead Restore in iTunes. When you reach the point where iTunes asks if you want to restore from a backup or set it up as new, then unplug the iPhone from iTunes. Done!

    Please explain why erasing from settings is a waste of time?

    Depending on how much stuff you have on your iPhone, an erase directly from the iPhone can take from 10-15 min to hours.
    Using the restore in iTunes-method takes 15 min tops. Regradless of how much data you have on the iPhone.

    As has been mentioned before, if you have iMessage set up it can be a problem if you don't do a full and complete restore via iTunes. Many, MANY people have reported this as being an issue. Unfortunately it's Apple dropping the ball here. I don;t believe we should have to do it this way, but it is what it is.

    What's the best thing about forums on the internet you ask?

    The best thing is when you spend time helping others with their problems, and rarely get a "thanks" or just a comment in return. Absolutely love it!

    Depending on how much stuff you have on it. But yes iPhone 4/4S is of course quicker then 3G and 3GS.
    And just to be clear; we are talking about the "delete all content and settings", right?

    Hi thanks for the info above. I'd like to clarify two points if I may.

    "When you reach the point where iTunes asks if you want to restore from a backup or set it up as new, then unplug the iPhone from iTunes. Done!"

    So you just unplug not selection either option ?

    Will performing this operation corrupt my itunes library/iphone back up at all.

    I don't want to loose any of the data/photos/music from my iPhone 4 that I want to synch up to my new iPhone 5 ?

    Thanks.

    You MUST turn off iMessage first so it de-registers the phone. Otherwise it will still get your messages.

    Also did erase from phone on a nearly full 32GB iPhone 4. Took a few seconds and everything is definitely gone. ITunes restore is annoying, especially since it usually requires you to redownload the iOS image first.

    Erase content iphone 4S

    I have a 4S and need to erase content and settings as part of the unlock process. Problem is, we've already switched to a new carrier and this phone has no service. Each time I try to erase or restore or anything it gives me a message reminding me I'm not online. Is there a way to erase content and unlock the phone while offline?
    I see all the messages about "erase all content and settings" but this presumes an online connection.

    I'm about to be boarding that same boat here shortly. I'm getting ready to unload my old JB'd/UL'd 4s and want to 'clean' it w/o removing the jailbreak aspect. Which way will do what I'm after?
