I realize you were not suggesting to buy the Bionic. I read that unless a chip was placed in the phone, that downloading the app will prove ineffective. I know that the Bionic has it, but not sure if the 4 does.
The tech people in NYC are not the most knowledgeable; in fact, I've taught them I thing or two. You should see the look they give me once they find out what I know about the phone. The phones are locked to the display so a sales person would have to get a tech person to look at it. If the techs are busy, then that will be a slim chance. But I will try my best to download it on my own and then approach the tech person myself. I'll keep up you posted.
