I'm sending my (unrooted) nexus s off repair under under warranty, and was just wondering if there any precautions I can take to limit the amount of personal info on the device, lest the engineers take a look through my contacts/emails etc.? (ideally without resetting phone to factory defaults)

Main ideas I've had so far are:

  • Associating the phone with a brand new google account and deleting the old ones
  • Moving all sd card content to computer
  • Clearing caches

Resetting the phone to factory settings (Menu -> Settings -> Privacy -> Factory data reset) and wiping the microSD card (after backing up its contents) should be all that's needed.

Factory reset dis-associates the phone from your Google account, removes any custom apps (installed on internal memory) with their data, and clears all the caches.

P.S. There is a good chance that the manufacturer (Samsung in your case) or whoever you are sending your phone to for repairs might send you a different handset. Depending on their service terms, they may simply ship you a brand new Nexus S, or even a refurb. So jumping through hoops to leave your installed apps intact might be a waste of time.

Basically, it looks like you want to clear everything except your apps. Is that right? If so, I'd just use something like App Manager to back them all up, and then do a factory reset. If you back them up to the SD card they should be safe, but you can always copy the backup to your computer.
