Cracked your Palm Treo? That’s really too bad. But you can always replace it! Find a reliable place on the Internet where you can buy the housing, then get to tinkering!
Prepare your new Treo housing!
Now remove the stylus, your memcard, and your SIM card from your phone.
Then remove the battery.
With a screwdriver, remove all seven screws so you can pry your phone apart.
When the screws are gone, pull apart your phone.
Ready to transfer, yeah?
Disconnect the ribbon cable from the internal circuit board next.
Flip over the main board, and you will see the LCD screen and the keyboard. Remove the cable connecting the board to the LCD. The board is now all disconnected.
Now, remove the screws connecting the keypad to the cover.
Now you can replace the cover! Put the board into the new housing and reconnect the cables.
Transfer the speaker and LCD screen to the new unit. Put the two pieces together, and screw the back cover in place.
There you go! 
If you are looking to replace the screen on your Treo, follow the instructions below.
