Performing a hard reset on a Treo 650will erase everything on the smartphone. Most people do this because of trouble with the Treo 650's software. There are several key stages to performing a hard reset. Follow these steps to learn how to do it properly.
  1. HotSync the Treo 650 to your computer to ensure that you have all of your information backed up. You will lose everything on your Treo 650 with a hard reset.
  2. Step 2 Press and hold down the red phone key on the right side of the Treo 650 keyboard until the Palm screen appears. This will begin the hard reset.
  3. Step 3 Let go of the red phone button when you see the Palm screen.
  4. Step 4 Read the screen prompt carefully. It will ask you to press the up arrow key to proceed with the hard reset or the down arrow key to abort. Press the up arrow to continue with the hard reset.
  5. Step 5 Wait for the phone to reboot. When it comes back on, it will ask you to select a language and walk you through the same introductory screens you saw when you first got the phone.
  6. Step 6 HotSync your Treo 650 to your computer. When prompted, select your old username to restore all of your contacts and information. This should complete the hard reset process.

Old Treo 650, with slight deterioration to screen.

I believe that serial numbers are different for everything and that only model numbers stay the same. Most likely, the screen will work.

Unlocked Treo 650 wont send text messages

I have the same problem using an unlocked Treo 650 on O2(UK).
One thing you need to do is make sure that the Message Centre Number is set correctly for the SIM network you are using. Get the MCN from the internet, then on the Treo Messaging > Menu > Options > Preferences > Network > Manual > Edit to check/set the MCN.
