How do I do a FACTORY RESET

[tiki]

I am sending my G1 back for an exchange- I want to clear this thing out before I send it off..

Anyone know how to do a factory reset?

nm found it under home>settings>phone storage

make sure your phone is off

hold the home button and the power button for 15 or so seconds, past the t-mobile g1 loading screen...

you'll see a screen with an arrow pointing to the g1, press the home and power button again and it should start a factory reset

Will all personalisation and data be wiped?

Also what happens to APN number as I've especially set up Australian Optus APN number etc?

Anything that is saved on the phone memory will be wiped! So anything on your SIM or memory card should be fine.

Thanks very much.

A question is about some preloaded APP is located on /data/app.
If I do Factory Reset, the preloaded app will be erased, right?
Or it will be kept?
