One of the things I really miss about my Palm pre is the touchstone charger. Why every phone doesn't offer it is beyond me
Anyway, I decided to adapt one of my old pre touchstone backs to my Trophy.
I carefully removed the inductive coil assembly with a razor blade:
The bottom terminal in the pic is positive the top is negative.
The whole thing comes off like a sticker. Just start at the corners and carefully peel it off.
I then aligned it and stuck it on the inside of an Incipio Sylicrylic case:
It may work using the factory back but the silicone part of the case made routing wires easier. I left the factory back off to give more room.
Here are the places where I wired the charger:
Pic ripped off the web
The square on the left (Near the vibrator) marks a tiny SMT component that is the positive from the wired charger. The square on the right is a common ground.
Some poking around with a meter will reveal the exact places. You should have 5V with the USB charger plugged in. I just used some phone wire stripped down and soldered them in place.
So far it works great Sorry about the pics but they were taken with my Trophy. It's my only camera so I couldn't take pics of the inside :blush:
This video was VERY useful:

Hopefully this will help some other Palm rejects enjoy their Trophy even more
