I hope this is the correct location for my question.

 

I've done a number of searches on how to reset my iPhone before selling it.  I have already reset the iPhone via General/Settings/Reset/Erase All Content and Settings.

 

Is there anything else that can to be done to fully erased any other data that maybe available?  I did read somewhere but wanted to get some expert advise on this and whether it is necessary to do any further steps.  If so, please could you provide non-technical steps?

 

Thank you.

    The option you selected should be sufficient. You can restore the iPhone to factory settings if you wish:

    but I don't know what else that might do that would be of any benefit.

    This link is for iTunes: Backing up, updating, and restoring iOS software.  This is not what I want to do.   I've already Erased All Content and Settings.

     

    But I read there is a 2nd step - https://securosis.com/blog/formatting-an-iphone-to-wipe-data

     

    What is your opinion?

    The link is for exactly what I suggested, restoring the iPhone to factory settings which reinstalls the OS, erasing everything that's on it. Again, I think it not really needed, but you can do it if you wish to give the purchaser a "fresh" iPhone.

     

    As to the "2nd step", I think that procedure unnecessary and probably ineffective. But if you're really concerned about residual data, there's no harm in it.

     

    Regards.

    Please can you advise further...  I will try the "2nd step".  The problem is that I have now moved to the iPhone 4 and havent used the iPhone 3 for months.  Step 1 states 'Restore the iPhone from within iTunes.'.  I am fairly sure that in the past, when I plugged in the iPhone, it would automatically start syncing.  If thats the case, then I wouldnt have 'time' to carry out Step 2, On the “Info” tab, un-check all options so you don’t synchronize calendars, email, bookmarks, and contacts."  How can I can this please?

     

    Sorry if a silly question, but i've only used iTunes at a basic level, and worried I may corrupt my exising backup for my Iphone 4.

    Synching the IPhone 3GS should not affect the iPhone 4 in any way. So just follow the instructions given on that web site, if you really want to do that. You can always cancel any initial sync that the system attempts when you first connect the iPhone by clicking the "x" in the window at the top of iTunes. Then you can restore the iPhone and use those "step 2" instructions. Or you can go to the iTunes preferences, select Devices, and checkmark the option to prevent devices from synching automatically, at least until you get the old iPhone cleared.

     

    Regards.

    Thanks... I created a Playlist with all my songs (1599) and that fill the Storeage Bar still have 4GB free.  I created a second copy of the Playlist and added that to the sync but still have the 4GB free.  The instructions say fill it up so it looks full.  I tried adding smaller playlists but it does 'fill up' the 4GB free space.  Any ideas why?

     

    Also my email mailbox is still there.  Do I delete manually?  I did click 'Register' later as that was an option when following these steps.

     

    Thank you.

    Just finished copying over the songs, still with 4GB left. I tried adding further playlists but that 4GB doesn't decrease.

     

    Should I now just do "Erase All Content and Settings" again? to returnto 'fresh iphone?

     

    Thanks again for helping.
