Internet Tethering: Using Smartphone as a Modem

Hard reset the phone by holding down UP and POWER to boot. It will ask to confirm.

You can adjust the brightness of the screen in Settings under Power (scroll down)

Pressing and holding the Home button brings up the task manager

• Pressing and holding the jog dial brings up a list of apps
• Pressing the power button brings up the quicklist
• Hold down message key to turn off backlight on screen.
• Fn + B = Toggle Bluetooth

Press the V key for PAGE DOWN and the T key for PAGE UP.

Hold down any key while typing to get its “alternate” character. i.e. Hold down the Q for a moment and you’ll get the + symbol. This is nice if you don’t like hitting Caps/Shift Q to get it.

If you are reading an email, press the center d-pad “action” button… it will take you to the new contact entry with that persons email address already filled in.

Apparently the phone doesn’t support automatic keylock, you have to hold down the “end call” key for 3-4 seconds and it locks the phone.

When you have a URL in the address bar hold down the BACK button above the red hang up button and it will delete the entire URL.

In any of the edit fields (contacts, I.E., and others) if you hold down Undo (top right U-Turn with an arrow) it will delete the contents of the field you are in.

There is no way to get periodic reminder tones for missed calls or messages. This little app addresses that deficiency.

Holding down the back button on the right hand edge of the device launches the Camera app for taking pictures.
