Finally got a 4 from ebay after having my 3gs for a couple years.
Cancelled my exisiting 02 rolling and opted for a giffgaff thing for the 4, till something better comes out next year or whenever.
I would like to
1) save all my 3gs content onto my computer
2) plug in my 4 to the laptop, to download the latest update, BUT want nothing, including my contacts, from the 3gs to be on my 4
3) delete all content from my 3gs so I can sell it on
I don't plug in my iphone too often to the laptop, so don't have much of a clue
So, do I plug my 3gs, drag and drop all pics, music to my laptop, then delete the old itunes. Then plug in my 4 afresh, let the new itunes download and new software update? Then somehow factory reset the 3gs?
Clueless, as you can tell, please help!
