I am wondering what phones have batteries that would work in the sensation?? I know the EVO 3D would work. I put myself in a situation. I had a warranty exchange done through TMobile. I got the new phone in and traded it off before I put my current Sensation back to S-OFF to send it in to TMobile. Now I need to find a way to put the thing back to S-On before sending it back to TMobile. I know some sensations come shipped S-Off. But even still, I have CM7 flashed on it now. I would need to flash a stock rom back on it before I sent it back or they will charge me full price for the phone. Any suggestions are greatly appreciated. Thanks guys. I already know this was an Idiotic mistake on my part...lol
