Will a factory reset clear my device?

[marneedshelp]

Trying to remove personal things off of my phone to return it (got a replacement).  Will resetting it to factory defaults do this?  Specifically, facebook and email needs to be removed.

Doing a factory reset will remove all of your info from the phone and put it back like it was 'out of the box'.  Be sure to remove your SD card first to be on the safe side (you'll want it for the replacement phone anyway, along with your SIM card).
