+1 i had totally forgoten about trying to use the touchstone charger til i saw this. i use to sell them so i picked up a few from other stores and tried this out myself and im glad to say that it worked for me as well. i had to use a pixi back though.

I was able to do this mod to my Incredible 2. I was able to plug in the charger and test the points on the back of the phone to determine polarity for my mod.

I am now trying to do this on my Droid 3. Only issue I am having is that when plugged into the charger the leads are set up like so.

1 2 3 4

Now testing across leads 1 and 2 I get 1.6v with #2 being the positive lead. Now after more testing it seems like #2 is the only positive lead??? can this be? Am I testing it wrong?

Before trying to find the power lead, have you nailed down the ground? That's much easier to test for. Just find USB ground or any other ground in the phone and see which pins are grounded out. from there you might have better luck with finding power.

PS. An inductive charge back cover for your droid 3 costs $10 from verizon. Buy that, strip out the old internals, test those, then put in the palm pre ones in place of that. Problem solved, and no unslightly bulges from not having enough room in the stock case.

Sorry to bump an old thread But has anyone tried the induction back cover sold by verzion for the charge and used it with any mods with the touchstone "puck" wireless charger? Thanks

Bump. Vzw Droid charge inductive backs are on eBay ~$14usd. If compatable would be easy fix.

Edit: ordered the pieces, will try out and update. Curious if the contact points can be removed to use for other Verizon inductive ready devices like s3.

Okay please let me know!

No dice. Official verixon droid charge back and oem palm touch stone.

Have to still test it with a multi meter, so stay tuned. It might be as simple as palm has the opposite polarity then the verixon charging pad.
